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, an hundred and thirty and seven years: and he gave up the ghost and died; and was gathered unto his people.
18 And they dwelt from Havilah unto Shur, that is before Egypt, as thou goest 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 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 be so, why am I thus? And she went to inquire of the Lord.
