16 These are the sons of Ishmael, and these are their names, by their villages and by their encampments (sheepfolds)–twelve princes according to their tribes. [Foretold in Gen. 17:20.]
17 And Ishmael lived 137 years; then his spirit left him, and he died and was gathered to his kindred.
18 And [Ishmael's sons] dwelt from Havilah to Shur, which is before Egypt in the direction of Assyria. [Ishmael] dwelt close [to the lands] of all his brethren.
19 And this is the history of the descendants of Isaac, Abraham's son: Abraham was the father of Isaac.
20 Isaac was forty years old when he married Rebekah, the daughter of Bethuel the Aramean of Padan-aram, the sister of Laban the Aramean.
21 And Isaac prayed much to the Lord for his wife because she was unable to bear children; and the Lord granted his prayer, and Rebekah his wife became pregnant.
22 [Two] children struggled together within her; and she said, If it is so [that the Lord has heard our prayer], why am I like this? And she went to inquire of the Lord.
