These are the sons of Ishmael and these are their names, by their villages and by their encampments, twelve princes according to their tribes.
(This is the length of the life of Ishmael, one hundred thirty-seven years; he breathed his last and died, and was gathered to his people.)
They settled from Havilah to Shur, which is opposite Egypt in the direction of Assyria; he settled down alongside of all his people.
These are the descendants of Isaac, Abraham's son: Abraham was the father of Isaac,
and Isaac was forty years old when he married Rebekah, daughter of Bethuel the Aramean of Paddan-aram, sister of Laban the Aramean.
Isaac prayed to the Lord for his wife, because she was barren; and the Lord granted his prayer, and his wife Rebekah conceived.
The children struggled together within her; and she said, "If it is to be this way, why do I live?" So she went to inquire of the Lord.
And the Lord said to her, "Two nations are in your womb, and two peoples born of you shall be divided; the one shall be stronger than the other, the elder shall serve the younger."
When her time to give birth was at hand, there were twins in her womb.
The first came out red, all his body like a hairy mantle; so they named him Esau.
Afterward his brother came out, with his hand gripping Esau's heel; so he was named Jacob. Isaac was sixty years old when she bore them.
