16 These were Ishmael’s sons, and these are the names of the tribal leaders listed according to their settlements and camps.
17 Ishmael lived one hundred thirty-seven years and then breathed his last breath and died.
18 His descendants lived from Havilah to Shur, which is east of Egypt stretching toward Assyria. They often attacked the descendants of his brothers.
19 This is the family history of Isaac. Abraham had a son named Isaac.
20 When Isaac was forty years old, he married Rebekah, who came from Northwest Mesopotamia. She was Bethuel’s daughter and the sister of Laban the Aramean.
21 Isaac’s wife could not have children, so Isaac prayed to the Lord for her. The Lord heard Isaac’s prayer, and Rebekah became pregnant.
22 While she was pregnant, the babies struggled inside her. She asked, “Why is this happening to me?” Then she went to get an answer from the Lord.
