16. These are the sons of Ishmael, and these are their names, by their towns, and by their encampments; twelve princes according to their nations.
17. And these are the years of the life of Ishmael, a hundred and thirty-seven years: and he breathed his last and died; and was gathered unto his people.
18. And they dwelt from Havilah unto Shur, that is beside Egypt, as you go toward Assyria: and he died in the presence of all his brethren.
19. And these are the generations of Isaac, Abraham's son: Abraham begat Isaac:
20. And Isaac was forty years old when he took Rebekah to wife, the daughter of Bethuel the Aramean of Paddanaram, the sister to Laban the Aramean.
21. And Isaac entreated the LORD for his wife, because she was barren: and the LORD was entreated of him, and Rebekah his wife conceived.
