Gen. 17:4‑5,16,20• 4As for me, behold my covenant is with thee, and thou shalt be a father of many nations.
5Neither shall thy name anymore be called Abram, but thy name shall be Abraham; for a father of many nations I have made thee.
16And I will bless her, and give thee a son also of her; yea, I will bless her, and she shall be a mother of nations: kings of people shall be of her.
20{i}And for Ishmael I have heard thee: behold, I will bless him, and will make him fruitful, and will very greatly multiply him; twelve princes shall he beget, and I will make him a great nation.{/i} (Gen. 17:4‑5,16,20)
Gen. 25:1‑34• 1And Abraham took another wife, and her name [was] Keturah.
2And she bore him Zimran and Jokshan and Medan and Midian and Ishbak and Shuah.
3And Jokshan begot Sheba and Dedan; and Dedan's sons were Asshurim and Letushim and Leummim;
4and Midian's sons, Ephah and Epher and Enoch and Abidah and. Eldaah: all these [were] Keturah's sons.
5And Abraham gave all that he had to Isaac;
6and to the sons of the concubines that Abraham had Abraham gave gifts, and, while he yet lived, sent them away from Isaac his son, eastward to the east country.
7And these [are the] days of the years of Abraham's life which he lived, a hundred and seventy-five years.
8And Abraham expired and died in a good old age, an old man and full, and was gathered to his people.
9And Isaac and Ishmael his sons buried him in the cave of Machpelah, in Ephron's field, son of Zohar the Hittite, which [is] before Mamre,
10the field which Abraham bought of the sons of Heth: there was buried Abraham, and Sarah his wife.
11And it came to pass after Abraham's death that God blessed Isaac his son; and Isaac dwelt at Beerlahai-roi
12And these [are] Ishmael's generations, Abraham's son, whom Hagar the Egyptian, Sarah's bondwoman, bore to Abraham.
13And these [are] the names of Ishmael's sons by their names according to their generations: Ishmael's firstborn, Nebaioth, and Kedar and Adbeel and Mibsam
14and Mishma and Dumah and Massa,
15Hadar and Tema, Jetur, Naphish and Kedemah.
16These [are] Ishmael's sons, and these their names in their villages and in their encampments, twelve princes according to their peoples.
17And these [are] the years of the life of Ishmael, a hundred and thirty-seven years; and he expired and died, and was gathered to his people.
18And they dwelt from Havilah to Shur which [is] before Egypt, as thou goest toward Assyria . He settled before all his brethren.
19And these [are] the generations of Isaac, Abraham's son. Abraham begot Isaac.
20And Isaac was forty years old when he took Rebecca as wife, daughter of Bethuel the Syrian of Padan-Aram, sister of Laban the Syrian.
21And Isaac entreated Jehovah for his wife, because she [was] barren; and Jehovah was entreated of him, and Rebecca his wife conceived.
22And the children struggled together within her; and she said, If so, why [am] I thus ? And she went to inquire of Jehovah.
23And Jehovah said to her, Two nations [are] in thy womb, and two peoples shall be separated from thy bowels; and [one] people shall be stronger than [the other] people; and the elder shall serve the younger.
24And when her days to be delivered were fulfilled, behold, twins [were] in her womb.
25And the first came out red all over like a hairy garment; and they called his name Esau.
26And after that came his brother out; and his hand took hold of Esau's heel; and his name was called Jacob; and Isaac [was] sixty years old when she bore them.
27And the boys grew; and Esau became a man skillful in hunting, a man of the field, and Jacob an upright man dwelling in tents.
28And Isaac loved Esau because venison was to his taste , and Rebekah loved Jacob.
29And Jacob boiled a dish , and Esau came in from the field, and he [was] faint.
30And Esau said to Jacob, Feed me, pray, with the red—the red thing there, for I [am] faint. Therefore they called his name Edom.
31And Jacob said, Sell today thy birthright to me?
32And Esau said, Behold, I am going to die, and what [is] this birthright to me?
33And Jacob said, Swear to me today, and he swore to him; and sold his birthright to Jacob.
34And Jacob gave to Esau bread and the dish of lentiles; and he ate and drank and rose up and went away: thus Esau despised the birthright. (Gen. 25:1‑34)
