The Allegory of Two Wives

 

Lamech the Elder and his 2 wives. Lamech was an early Hebrew ruler.


Dr. Alice C. Linsley

The Hebrew rulers who controlled territories and water systems had two wives. The separate settlements of the wives marked territorial boundaries of the ruler’s kingdom. This feature of the Hebrew social structure sheds light on the relationship of the faithful among the Hebrew (before Judaism) and the faithful among the people who identify as Christians.

The Apostle Paul draws on the Hebrew social structure to contrast Judaism with the core Christian belief that the gift of salvation is embraced by faith in God's promises. In Galatians 4:21-31, Paul uses the story of Sarah and Hagar to illustrate the difference between salvation by grace through faith in Christ and the Jewish emphasis on salvation through obedience to the law. Sarah's son Isaac is portrayed as the child of promise, while Hagar's son Ishmael is portrayed as a slave to the law.

In Paul's context, the allegory makes sense. He was an apologist for the Messianic Faith that was fulfilled in Jesus Christ. He insisted that only those who believe that Jesus is the Son of God who came to save sinners can receive the promise of salvation. Paul was arguing with Jews who had rejected Jesus as the Messiah and Son of God. 

Paul also states that those who would be saved must be grafted into the faith of Abraham. Abraham and his Hebrew ancestors believed in God Father and God Son. They also believed in bodily resurrection and looked for a righteous ruler who would overcome death and rise on the third day. The earliest known resurrection texts were prayers offered by Nilotic Hebrew priests for their deceased rulers.

Paul contrasts Sarah, Abraham's principal wife and Hagar, a concubine. His allegory involves two women of unequal social status. Yet another allegory should involve Abraham's two wives, Sarah and Keturah. Both were Hebrew women who held to the faith of their Hebrew ancestors. Sarah was the wife of Abraham's youth and Keturah was the wife of Abraham's old age. Abraham had 9 sons and an unknown number of daughters by 2 wives and 2 concubines (Hagar and Mesek).

Sarah was Abraham's half-sister and Keturah was Abraham's patrilineal cousin. These two Hebrew wives pose an allegory of the relationship of the people of faith who lived in anticipation of the Son's appearing and those who lived after the Son's appearing. Sarah came first and Keturah came much later, but both were women of the Hebrew faith. In other words, as 2 wives made a kingdom for Abraham, so the kingdom of God is comprised of 2 wives. One does not outrank the other or supplant the other. We are not speaking of Israel and the Church. Instead, the allegory to 2 wives represents the faithful justified who believed God's promise concerning the Son yet to appear and the faithful justified who love and obey the Son Incarnate. 

The social structure of the biblical Hebrew tells us much about the relationship between the two households of faith. Together they constitute a kingdom. There is no reason to subsume one household of faith to the other. They are equal in God's kingdom.

Hagar's Conversion


Painting of Hagar in the wilderness by Giovanni Lanfranco. It hangs in the Musée du Louvre.


Alice C. Linsley

Hagar was the Egyptian handmaiden to Sarah, Abraham’s sister wife. She was also one of Abraham’s concubines. Though she is presented as a downtrodden slave, it is likely that Hagar was highly cultured and moved comfortably in the circle of nobles.

As the Horite Hebrew clans practiced endogamy, it is likely that Hagar was the daughter of a Horite Hebrew priest, and as such, she would have been a skilled attendant to Sarah, and even as a concubine, she would have been a woman of high social status.

Sarah’s resentment toward Hagar appears to have had a long history. Some of the resentment may have been cultural. Sarah was from the region of Aram in Mesopotamia while Hagar is identified as an Egyptian. Sarah's resentment toward Hagar became blind jealousy after Isaac was weaned, when Ishmael was about 15 years old.

Genesis portrays Hagar as having a complex personality. In later life she is a strong and independent woman, contracting marriage for her son and apparently producing other offspring known as the Hagarites. They are mentioned in Psalm 83:6. The core of this psalm is believed to pre-date David. The Hagarites are distinct from the Ishmaelites in the Psalm 83 listing of allies, so it is apparent that Hagar (like Anah and Oholibamah) was regarded as a clan chief.

This picture of Hagar as a mature clan chief differs from the picture presented in Genesis 16:5 where we are told that Hagar acted tactlessly toward her childless mistress. Sarah blamed Abraham for this and Abraham said to Sarah: “Your slave-girl is at your disposal. Treat her as you think fit” (Genesis 16:6). Sarah then abused Hagar who fled to a spring where Abraham had lived for a time (Genesis 20:1). The Angel of the Lord found her at the spring and prophesied concerning her son that his name should be Ishmael meaning God Hearkens, for God heard the cry of Hagar's affliction.

This story portrays Hagar as a tactless, abused runaway, but note how she has a personal encounter with the Lord at the water shrine! She knows that she has encountered the all-Seeing God because she declares that she has gone on seeing, even as she is seen (Genesis 16:14). The Angel of the Lord speaks in the first-person, and in verse 13 Hagar identifies the visitor as God. To me, this sounds like a conversion story.

Given the times in which Hagar lived, she would have run to a place where she felt she could provide for her son. She traveled to a shrine half way between Kadesh and Bered (Genesis 16:14). In Genesis, when a water system is identified as being along a road between two towns, it is a shrine to which a priest is attached. It is likely that Hagar had family there. Since this was Horite Hebrew territory, an Egyptian priest (Harwa) at a water shrine would have been a Horite priest.

Horite territory extended north-south at least between Mount Hor (above Kadesh-barnea) and Mt. Harun or Hor south of Oboth. According to Genesis 14: 6, Horite territory extended as far south as the wilderness of Paran (see map).


A temple dedicated to Hathor, the mother of Horus was discovered at the southwestern edge of Mt. Timna by Professor Beno Rothenberg of Hebrew University. This is the site of some of the world's oldest copper mines.

Horite priests were devotees of Horus, who was called “Son of God.” From ancient Egyptian texts we gather that Horus is equal to the Father in nature and glory. The Ancient Egyptian Coffin Texts and Pyramid Texts provide a great deal of information about Horus, the divine son of Ra. This is expressed in the Ancient Egyptian Pyramid Texts. In the priest's prayer to the King, he says, "Horus is a soul and he recognizes his Father in you..." (Utterance 423).

In these texts Horus is described as the one who unites the peoples (the Upper and Lower Nile). This is symbolized by the double crown. The rulers of the two regions wore different crowns, but Horus was called "Horus of the Two Crowns" because he wore both. This is what stands behind the account of Yeshua/Joshua, the priest, receiving the "crowns" in Zechariah 6:11: "Take the silver and gold, and make crowns, and set it upon the head of Joshua the son of Jehozadak, the high priest..."

A reference to the third day resurrection is found in the Pyramid Texts: "Oh Horus, this hour of the morning, of this third day is come, when thou surely passeth on to heaven, together with the stars, the imperishable stars." (Utterance 667)

Consider how Horus describes himself in the Coffin Texts (148):
I am Horus, the great Falcon upon the ramparts of the house of him of the hidden name. My flight has reached the horizon. I have passed by the gods of Nut. I have gone further than the gods of old. Even the most ancient bird could not equal my very first flight. I have removed my place beyond the powers of Set, the foe of my father Osiris. No other god could do what I have done. I have brought the ways of eternity to the twilight of the morning. I am unique in my flight. My wrath will be turned against the enemy of my father Osiris and I will put him beneath my feet in my name of ‘Red Cloak’.

This text is about 1000 years older than the words of Psalm 110:1, a clear messianic reference: The Lord says to my Lord: “Sit at My right hand until I make your enemies a footstool for your feet."

Horus was expected to trample down the serpent. This expectation is expressed int he Pyramid Texts:
"Horus has shattered (tbb, crushed) the mouth of the serpent with the sole of his foot (tbw)" Utterance 388 (681).

This reference dates to about 800 years before Psalm 91: ""They will bear you up in their hands, That you do not strike your foot against a stone. You will tread upon the lion and cobra, The young lion and the serpent you will trample down."

Horus gives himself as mystic food of immortality. In The Pyramid Texts, dating from the beginning of the 4th Dynasty, we read: "O Hunger, do not come for me; go to the Abyss, depart to the flood! I am satisfied, I am not hungry because of this kmhw-bread of Horus which I have eaten." (Utterance 338) The Egyptian word km means to bring to an end, to complete, or fulfill, and hw refers to the heavenly temple or mansion of the firmament above.

It appears that the "kmhw-bread of Horus" is what the Church Fathers call "the bread of immortality." Concerning himself, Jesus said that "unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day" (John 6:53-54).

These are key elements of the Messianic Faith by which Messiah is identified.

Jesus Messiah is sometimes called “the Angel of the Lord.” Perhaps he met Hagar’s when she fled to the Horite shrine. Might Hagar's conversion be due to a personal encounter with the pre-incarnate Christ? 

This is how some Church Fathers see Hagar's visitation. He who is of one essence with the Father, “for in Him dwelleth all the fullness of the Godhead bodily” (Col. 2:9) came into the world to save sinners like Hagar... like me.

The Years of Waiting for the Promised Heir


Now Sarai, Abram’s wife, had borne him no children. But she had an Egyptian slave named Hagar; so she said to Abram, “The Lord has kept me from having children. Go, sleep with my slave; perhaps I can build a family through her.”

Abram agreed to what Sarai said. So after Abram had been living in Canaan ten years, Sarai his wife took her Egyptian slave Hagar and gave her to her husband to be his wife. He slept with Hagar, and she conceived. (Genesis 16:1-4)


Alice C. Linsley

Abraham is a pivotal figure of history. He is a sent-away son who established control over a territory that extended between Kiriath-Arba (Hebron) and Beersheba. His territory was entirely in the region of ancient Edom (Idumea) and he was kin to the Horite rulers of Edom listed in Genesis 36.




Abraham's first wife was Sarah, his half-sister. Sarah resided in Hebron. His second wife was Keturah, one of his patrilineal cousins. Keturah resided in Beersheba. Both Hebron and Beersheba were in the land of Edom, called "Idumea" by the Greeks. Idumea means "land of red people." Abraham's territory extended between the settlements of his two wives and was entirely in Edom.

It was the norm for Habiru rulers to have two wives. They often had two concubines also. Abraham's concubines were Hagar, the mother is Ishmael, and Masek, the mother of Eliezer. Neither of these sons was the "proper heir" to Abraham according to the Habiru marriage and ascendancy pattern. Eliezer was Abraham's heir according to Horite law, only until Issac was born. The proper heir for the Horite Habiru rulers was always the first born son of the half-sister wife.

According to Genesis 16, Sarah was barren and had given up hope of having a child. This is after she and Abraham had been living in Canaan for 10 years. During those years Abraham had already taken his second wife, Keturah. She born Joktan (Yaqtan), Abraham's first born son. However, Joktan was not Abraham's proper heir. As the son of the cousin bride, Joktan was named after his maternal grandfather in whose kingdom he would serve as a high ranking official. According to Genesis 25, Keturah bore Abraham six sons: Joktan, Yisbak, Midian, Zimran, Medan, and Shuah. The name Yishbak means “sent away.”

Abraham had four first born sons: Joktan, Ishmael (Yishmael), Eliezer, and Isaac (Yitzak), probably born in that order. Joktan became the head of the Joktanite tribes of Arabia. Yismael became the father of the Sinai Bedouins. His Paran settlement was on the way to Egypt as indicated by these words: This is the genealogy of Ishmael, Abraham’s son, whom Hagar the Egyptian, Sarah’s maidservant, bore to Abraham. And these were the names of the sons of Ishmael: the firstborn of Ishmael, Nebajoth, then Kadar, Adbeel, Mibsam, Mishma, Dumah, Massa, Hadar, Tema, Jetur, Naphish and Kedemah. These were the sons of Ishmael and these were their names, by their towns and settlements… (Gen. 25:12-16).

No sons are named for Eliezer. He may have been a eunuch, not necessarily a castrated man, but perhaps one who is impotent, celibate, or not inclined to marry and procreate for legal reasons.

Yitzak fathered Jacob (Yacob/Yisrael), and Esau the Elder. Esau and Jacob were contemporaries of Seir the Horite, named in Genesis 36. The initial Y in these names indicates divine appointment by being overshadowed by the Sun. It is the symbol of the long horns of the bull and represents a solar cradle.

Clans related to Abraham's wife Keturah and her father Joktan the Edler

The first born sons ruled among the related clans of Horite Habiru. Abraham’s people. However, the first born sons of wives ranked above the first born sons of concubines. Joktan ranked over Eliezar, and Issac ranked over Ishmael. Joktan was a governor in the southern settlements of his maternal grandfather (Dedan, Ramaah and Sheba) and Isaac ruled the northern settlements of his father Abraham (Hebron, Beersheba, Gerar and Engedi).

Sarah's barren state would have caused her even greater misery after Abraham took his second wife and began to bear him sons. Here we find echoes of the Rachel-Leah conflict and the Hannah-Penninah conflict. In these narratives, the scorned or barren wife is vindicated by divine action on her behalf. Her long years of waiting were turned from sorrow to joy.

See the pattern? We await the return of the Promised Son, the Heir to the eternal kingdom. He has overcome death by death. He will turn our sorrow to joy and wipe away every tear.

Hagar's Journeys


Alice C. Linsley


Hagar was one of Abraham's two concubines and Sarah's handmaid. Abraham's son by Hagar was Yishmael (Ishmael) an Egyptian chief, as is evident by the initial Vav, a solar symbol designating a ruler. The Y indicates that he was a clan chief, as were these men: Yaqtan, Yisbak, Yitzak, Yacob, Yisra-el and Yeshua.

Yishmael's ethnicity was traced through his Egyptian mother, just as Jewish ethnicity is traced through the mothers. The idea that the Arabs come from Abraham by Ishmael is simply wrong. The Ar clans existed before the time of Abraham, and Abraham's Arabian descendants are traced through his first born son Yaqtan (Joktan). This is Yaqtan the Younger. He is named for his maternal grandfather in whose territory he would serve as a sort of Prime Minister.


Hagar's status

Hagar was a strong and sophisticated woman whose status actually increased once she left Sarah's service. She contracted marriage for her son with an Egyptian. This means that Yishmael's children were also Egyptian. 

After leaving Sarah, Hagar had other offspring known as the Hagarites. They are mentioned in Psalm 83:6. It is evident from this psalm that the Hagarites and the Ishmaelites were regarded as distinct clans and Hagar, like Anah and Oholibamah, was a clan chief.

This information provides an answer to the question raised by the angel: And the angel of the Lord found her by a fountain of water in the wilderness, by the fountain in the way to Shur. And he said, "Hagar, Sarai's maid, from where came you? and where will you go?" (Gen. 16:7-8)

Upon leaving Sarah's service, Hagar was at a pivotal point in her life. She needed to review her past and consider her future. She appears to have made the most of all the opportunities God presented her.


Hagar's route

Hagar fled from Hebron to Beersheba. Abraham had made this journey many times as he journeyed between the settlements of his two wives. Sarah resided in Hebron and Keturah resided in Beersheba. Abraham spent his old age in Beersheba.

The well at Sheba was very ancient. It was a water shrine under the control of Sheba, a Horite ancestor of both Abraham and Keturah. (Gen. 10:7) Sheba was the son of Ramah whose anceint priestly line was living in Ramah, the hometown of Elkanah and his two wives: Hannah and Penninah. Hannah was the mother of Samuel the Prophet. Penninah was the mother of Am-asi (I Chron. 2:25, 35). Am-asi is a Kushite name.

Beersheba and Kadesh were major water stations on the way to Egypt, so it appears that Hagar was returning to Egypt. The angel found her on "the way to Shur" (Darb el-Shur) which led from Beersheba to Kadesh-Barnea. From prehistoric times this route took travelers by year round water supplies. Flintstone tools dating between 80,000 and 16,000 BC have been found scattered around the area of Beerotayim (two wells). This is likely where the angel spoke to Hagar.

Archaeological surveys of the region have identified remains of structures on the eastern and western hills dating from the early and Middle Bronze Age. Hagar's route is indicated on the map as a dashed line.




Hagar's dismissal

Hagar apparently heeded the angel's advice and returned to serve Sarah. There she remained until Abraham agreed to send her and his son away. She second journey away from Hebron took her in a different direction. She headed to the desert of Paran where she lived with Ishmael who became a master archer. As with all sent-away sons, Ishmael receives his own territory.

It is likely that Abraham made provision for Hagar and Ishmael to join his kinsmen in the area of Timna, shown on the map at the bottom.

Timna or Tema plays an important role in early Biblical history. Known by Arabs as Taima, this water source lies about 70 miles north-east of Dedan. During the Chalcolithic Period, Kushite artisans settled in Paran where they lived in subterranean dwellings carved out of the limestone with metal tools. The Bible refers to these cave-dwellers as Dedanites. Dedan, Tema and Buz comprized a Horite confederation.

The oldest Arabic texts have been found around the North Arabian oases of Tema and Dedan. An ivory workshop was discovered in one of these dwellings at Bir es-Safadi.

Tema, Dedan and Dumah were caravan stops along the trade route from southern Arabia to Babylon. To this day, Joktanite clans reside in southern Arabia and Yemen.

Joktan is a variant of the name Jonathan, meaning "God gives." Joktan lived about 1987-1912 B.C. That he was a ruler is evident by the solar symbol Y at the beginning of this name. In early Arabian scripts, such as Thamudic, symbols represented complex ideas and experiences including names, attributes and worldview. A solar symbol such as Y or T or O represented a deified or divinely appointed ruler, his territory, his people, and his resources such as water and gold. This is why the Horite ruler-priests names begin with the solar symbol: Yaqtan, Yishmael, Yitzak, Yisbak, Yacob, Yosef, Yeshua, etc.

False Correlations

Alice C. Linsley

There is a good deal of misinformation about the connections between persons and deities of Hinduism and persons of the Bible. These are based on false or spurious correlations. Here are four examples:

#1: The Sanskrit word "Brahma" is a variant spelling of the biblical name Abraham.

This is incorrect.

The term "Brahma" is derived from the Proto-Dravidian root brih, which means to swell or enlarge. It is a reference to the Creator God whose emblem, the Sun, swells as it rises in the morning. The veneration of the rising Sun in Hinduism is expressed in the daily prayer ritual called Agnihotra.

The Old Arabic word for the swelling of the sun is yakburu, meaning “he is getting big” and with the intensive active prefix: yukabbiru, it means "he is enlarging." This has little connection to the name Abraham. However, it is rleated to the Proto-Dravidian word for a Sun temple, which is O-piru. Dravidian temples typically face east. The morning ritual of the priests was to greet the rising sun and watch as it expanded or swelled on the horizon.

There likely is a connection to the ancient Egyptian root bn, meaning to swell, and to the reduplicated form bnbn, but there is not an evident connection to the names Abram or Abraham.

In Hinduism, Brahma and his wife Saraswati are considered the founders of the worlds. In Genesis, Abraham is said to be the father of many nations. This is historically accurate since Abraham had many children, among them nine sons. Such a claim in not made in Genesis for Sara, however, since she gave birth to only one child, Isaac.

There is evidence of a common conception about ancestors who found nations, but an etymological connection between Abraham and Brahma, and between Sarai and Saraswati has never been demonstrated.


#2. The Sanskkrit word "Saraswati" is a variant spelling of the biblical name Sara

This is incorrect.

The Sarawati is a major river of India. The name of the river is a compound of two words: saras which refers to a body of water, and wati which is a Sanskrit suffix to indicate female gender.

Many rivers have "Sar" or Sara" as part of their names. Examples include the Sarawat River and the Saribas River in Borneo. Sarawat is also the name of the mountain range that borders the Red Sea in Yemen.

Sara is also Nilotic word associated with laughter (Gen. 18:12).The verb to laugh in Hausa, a Chadic language, is dara. Dara and Sara may be regarded as cognates since the letters d and s are interchangeable in Dravidian and in some African languages.

The Sarra are one of the largest population groups in Chad. Sara society is organized by patrilineal descent from a common male ancestor. There is a 3-clan confederation, such as characterizes Abraham's people. The qir ka are the eastern Sara, the qin ka are those living in central Chad, and the qel ka are the western groups. The Sara make up to 30% of Chad's population. About one-sixth of them are Christians and live in southern Chad.

The biblical name Sarah is also a title, meaning queen. It is derived from the Akkadian word for king which is šarru and the Akkadian word for queen which is šarratum.


#3. The Sanskrit word "Gayatri" is a variant spelling of the biblical name Keturah

This is incorrect. However, there is a parallel involving the idea of second or subordinate wives.

In Hinduism, Brahma's second wife is Gayatri. Attempts have been made to connect Gayatri with Abraham's second wife, Keturah. This assertion has no linguistic support. Keturah refers to fragrant incense or perfume. It is also possible that it refers to the Ketu people of Ra (God). The Ketu clans are known today as Ijebu (Nigeria) and may be related to the biblical Jebusites.


#4. The Sanskrit word "Ghaggar" is a variant spelling of the biblical name Hagar

This is incorrect.

The Ghaggar is a tributary of the Sarawati. Again, there is no relationship to the biblical name Hagar. Ghaggar is comprised of the words ghag-gar. The word ghag (also spelled khag) refers to river reeds, and gar means hidden. This is a description of how the Sarasvati dries up seasonally. It flows only during the Monsoon season, and at least half of the year it is marshy and full of reeds.

Who was Eliezer? Was He from Damascus?


William Dyce's oil painting of Eliezer (1860) 
is on permanent exhibit at the Minneapolis Institute of Arts.

"O Lord God, what can You give me seeing that I shall die accursed, and the steward of my household is Dam-Mesek Eliezer?" Genesis 15:2

The Hebrew is challenging here as there is an attempt at play on the sound ben meshek (son of Masek)... with dam mesek. It appears that Abraham had two concubines, Hagar and Masek. This was not unusual among the Habiru rulers. Consider Jacob's 2 concubines. 

The reference to Masek as a "handmaid" is clearer in the Orthodox Study Bible, based on the Septuagint. Genesis 15:2 reads: "And Abraham said, 'Lord, what will You give me, seeing I go childless, and the heir of my house is Eliezer of Damascus, the son of Masek, my domestic maid servant." The "of Damascus" is probably a mistake, but the Orthodox Study Bible committee decided to leave the place name.
If we include Eliezer as a son (following the Septuagint), Abraham had nine sons by two wives and two concubines. The first of the sons born to Abraham was Joktan (Yaqtan), son of Keturah.

Eliezer was Abraham's son by his concubine Masek (Mesek). He was one of the nine sons named in Scripture who were born to Abraham. However, his relationship to Abraham is only clear in the Septuagint. Bibles based on the Masoretic text do not include this information. The term dam means "blood" or "offspring" of Masek. Some Bibles have that Eliezar is from Damascus or that he is Damascene, but this is not implied in the older Greek version of the Old Testament.

To understand who Eliezar is and his importance, it is necessary to have some understanding of the marriage and ascendancy pattern of Abraham's Horim (called "Horites" in Genesis 36.)

Abraham had two wives, as was the pattern for Horite rulers. His father Terah had two wives. Sarah was Terah's daughter by one wife and Abraham was Terah's son by the other wife. This pattern of two wives meant that there were usually two firstborn sons; one by the half-sister wife and the other by the cousin/niece wife. As with all royal lines, there is problem when the wives are barren. 

In the Horite marriage and ascendancy pattern, the firstborn son of the cousin wife ascended to the throne of his maternal grandfather, after whom he was titled/named. Lamech the Younger (Gen. 5) ascended to the throne of Lamech the Elder (Gen. 4) Likewise, Esau the Younger ascended to the throne of Esau the Elder (Gen. 36). The first born sons of the cousin wives were not the proper heirs to the thrones of their biological fathers. Joktan, Abraham's first born son, the child of his cousin bride, Keturah, was never considered as Abraham's heir. He belonged to the household of Abraham's father-in-law.

The firstborn of the half-sister wife ascended to the throne of his biological father, so Isaac was Abraham's heir. However, he was not Abraham's firstborn. Neither was Ishmael. Ishmael was conceived late in Abraham's life, after Abraham had married Keturah. Keturah's firstborn son was Joktan (Yaqtan) of the Joktanite Tribes of Arabia. As Keturah was Abraham's cousin wife, Joktan ascended to the throne of his maternal grandfather.  

Sarah was barren. This meant that Abraham was without a proper heir, and growing desperate it appears. This is when he prayed about having an heir and received the promise (Gen. 15:4) that a son would come from his own "loins" (meaning blood descent from him and his half-sister).

Eliezar, as the firstborn of Masek, one of Abraham's concubines, was Abraham's only natural heir. Clearly before Isaac arrived, Eliezar was considered Abraham's rightful heir according to the Horite marriage and ascendancy pattern.

The name Eliezar/Eleazar appears twice in the Horite ancestry of Jesus Christ.
