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 to wife, the daughter of Bethuel the Syrian of Padan-aram, the sister to Laban the Syrian.
21 And Isaac intreated the LORD for his wife, because she was barren: and the LORD was intreated of him, and Rebekah his wife conceived.
22 And the children struggled together within her; and she said, If it be so, why am I thus? And she went to inquire of the LORD.
