16. These are the sons of Ishmael and these are their names, by their villages, and by their camps; twelve princes according to their tribes.
17. These are the years of the life of Ishmael, one hundred and thirty-seven years; and he breathed his last and died, and was gathered to his people.
18. They settled from Havilah to Shur which is east of Egypt as one goes toward Assyria; he settled in defiance of all his relatives.
19. Now these are the records of the generations of Isaac, Abraham's son: Abraham became the father of Isaac;
20. and Isaac was forty years old when he took Rebekah, the daughter of Bethuel the Aramean of Paddan-aram, the sister of Laban the Aramean, to be his wife.
21. Isaac prayed to the Lord on behalf of his wife, because she was barren; and the Lord answered him and Rebekah his wife conceived.
22. But the children struggled together within her; and she said, "If it is so, why then am I this way?" So she went to inquire of the Lord.
