Abraham takes another wife, Keturah, and she bears him six sons, among them Midian. He gives all he has to Isaac and gives gifts to the sons of his concubines, whom he sends eastward while he is still alive. Abraham dies in a good old age, at 175 years old, and is gathered to his people. Isaac and Ishmael bury him in the cave of Machpelah, beside Sarah. After his death, God blesses Isaac, who lives by Beer-lahai-roi.
The text lists the descendants of Ishmael, twelve princes according to their tribes, among them Nebaioth and Kedar. Ishmael dies at 137 and settles from Havilah to Shur, east of Egypt, opposite his kin.
Isaac, at forty, marries Rebekah, daughter of Bethuel the Aramean of Paddan-aram and sister of Laban. Rebekah is barren, and Isaac prays for her to the Lord, and Rebekah conceives. The children struggle within her, and she inquires of the Lord, who tells her that two nations are in her womb and that the older shall serve the younger. Twins are born: the first comes out red and hairy, and is named Esau; the second comes out with his hand holding Esau's heel, and is named Jacob. Isaac was sixty years old.
The boys grow up: Esau is a skillful hunter and a man of the field, and Jacob a quiet man dwelling in tents. Isaac loves Esau because he eats of his game, and Rebekah loves Jacob. One day Jacob is cooking stew and Esau comes in from the field exhausted. He asks for some of that red stew, which is why he is called Edom. Jacob asks him in exchange for his birthright, and Esau, saying he is about to die of hunger, sells it to him under oath. Jacob gives him bread and lentil stew, and Esau eats and drinks and goes his way, and the text concludes that he despised his birthright.
