13. and these are the names of the sons of Ishmael, by their names, according to their generations: the firstborn of Ishmael, Nebaioth; and Kedar, and Adbeel, and Mibsam,
14. and Mishma, and Dumah, and Massa;
15. Hadad, and Tema, Jetur, Naphish, and Kedemah:
16. these are the sons of Ishmael, and these are their names, by their villages, and by their encampments; twelve princes according to their nations.
17. And these are the years of the life of Ishmael, an hundred and thirty and seven years: and he gave up the ghost 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: he abode in the presence of all his brethren.
19. And these are the generations of Isaac, Abraham's son: Abraham begat Isaac:
20. and Isaac was forty years old when he took Rebekah, the daughter of Bethuel the Syrian of Paddan-aram, the sister of Laban the Syrian, to be his wife.
21. And Isaac entreated the LORD for his wife, because she was barren: and the LORD was entreated of him, and Rebekah his wife conceived.
22. And the children struggled together within her; and she said, If it be so, wherefore do I live? And she went to inquire of the LORD.
23. And the LORD said unto her, Two nations are in thy womb, And two peoples shall be separated even from thy bowels: And the one people shall be stronger than the other people; And the elder shall serve the younger.
