Genesis

¹⁶these are the sons of Ishmael, and these are their names, by their villages, and by their encampments; twelve princes according to their nations. ¹⁷And 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. ¹⁸And they dwelt from Havilah unto Shur that is before Egypt, as thou goest toward Assyria: he abode in the presence of all his brethren. ¹⁹And these are the generations of Isaac, Abraham's son: Abraham begat Isaac: ²⁰and 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. ²¹And Isaac entreated the Lord for his wife, because she was barren: and the Lord was entreated of him, and Rebekah his wife conceived. ²²And 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.
