Genesis 25:15-22
English Standard Version
Chapter 25
15Hadad, Tema, Jetur, Naphish, and Kedemah. 16These are the sons of Ishmael and these are their names, by their villages and by their encampments, twelve princes according to their tribes. 17(These are the years of the life of Ishmael: 137 years. He breathed his last and died, and was gathered to his people.) 18They settled from Havilah to Shur, which is opposite Egypt in the direction of Assyria. He settled over against all his kinsmen.
19These are the generations of Isaac, Abraham 's son: Abraham fathered Isaac,
20and 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.
21And Isaac prayed to the Lord for his wife, because she was barren. And the Lord granted his prayer, and Rebekah his wife conceived.
22The children struggled together within her, and she said, "If it is thus, why is this happening to me?" So she went to inquire of the Lord.
