And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.  And Abraham circumcised his son Isaac, after eight days, as God had commanded him.  And Abraham was an hundred years old when Isaac his son was born unto him (xxi. 2-5).  And the life of Sarah was an hundred and twenty seven years; these were the years of the life of Sarah.  And Sarah died in Kirjath-Arba, the same is Hebron in the land of Canaan” (xxiii. 1, 2).  Then comes the treaty of Abraham, reported with all due legal accuracy, with Ephron the Hittite, from whom he purchases the cave of Machpelah, which is over against Mamre, for a family burying-place (xxiii.).  “And these are the days of the years of Abraham’s life which he lived, a hundred and seventy five years.  And Abraham gave up the ghost, and died in a good old age, an old man and full of years; and was gathered to his fellow tribesmen.  And his sons Isaac and Ishmael buried him in the cave of Machpelah, in the field of Ephron ben Zohar the Hittite, which is before Mamre; the field which Abraham purchased of the sons of Heth; there was Abraham buried and Sarah his wife.  And after Abraham was dead, God blessed his son Isaac” (xxv. 7-11a).  Next come the Toledoth (generations) of Ishmael according to the regular practice of first exhausting the collaterals (xxv. 12-17).  “These are the Toledoth of Isaac the son of Abraham.  Abraham begat Isaac...and Isaac was 40 years old when he took Rebecca to wife, the daughter of Bethuel the Syrian of Padan Aram, the sister to Laban the Syrian....And Isaac was 60 years old when Esau and Jacob were born (xxv. 19, 20, 26c).  And Esau was 40 years old when he took to wife Judith the daughter of Beeri the Hittite, and Bashemath, the daughter of Elon the Hittite, and they were a grief of mind unto Isaac and to Rebekah.  And Rebekah said to Isaac, I am weary of my life because of the daughters of Heth; if Jacob also take such wives of the daughters of Heth, of the daughters of the land, what good shall my life do to me?  Then Isaac called Jacob and blessed him and charged him, saying, Thou shalt not take a wife of the daughters of Canaan; arise, go to Padan-Aram to the house of Bethuel thy mother’s father, and take thee a wife from thence of the daughters of Laban thy mother’s brother.  And El Shaddai will bless thee, and make thee fruitful and multiply thee, and give thee the blessing of Abraham, to thee and to thy seed with thee, that thou mayest inherit the land wherein thou art a stranger, which God gave unto Abraham.  And Isaac sent away Jacob, and he went to Padan-Aram unto Laban ben Bethuel, the Syrian, the brother of Rebecca, Jacob and Esau’s mother.  And Esau saw that Isaac blessed Jacob, and sent him to Padan-Aram to take him a wife from thence, and that as he blessed him, he gave him a charge, saying, Thou shalt not take a wife of the daughters of Canaan.  Now Jacob hearkened to his father, and went to Padan-Aram.  But Esau saw that the daughters of Canaan pleased
