16. These are the sons of Ishmael, and these are their names, by their towns, and by their castles; twelve princes according to their nations.
17. And these are the years of the life of Ishmael; a hundred and thirty and seven years: and he expired and died, and was gathered to his people.
18. And they dwelt from Havilah to Shur, that is before Egypt, as thou goest towards 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 Syrian of Padan-aram, the sister to Laban the Syrian.
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.
22. And the children struggled together within her: and she said, If it is so, why am I thus? And she went to inquire of the LORD.
