16 These are the sons of Ishmael, and these are their names, by their towns and by their palaces; twelve princes according to their families.
17 And these are the years of the life of Ishmael, one hundred thirty-seven years; and Ishmael expired 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 fell in the presence of all his brethren.
19 And these are the generations of Isaac, son of Abraham. Abraham begat Isaac;
20 and Isaac was forty years old when he took Rebekah to wife, the daughter of Bethuel, the Aramean of Padanaram, the sister to Laban the Aramean.
21 And Isaac prayed unto the Lord for his wife because she was barren; and the Lord accepted him, and Rebekah his wife conceived.
22 And the sons struggled together within her; and she said, If this is so, why should I live? And she went to enquire of the Lord.
