Genesis 25:20-22

21st Century King James Version

²⁰ And Isaac was forty years old when he took Rebekah for a wife, the daughter of Bethuel the Syrian of Padanaram, the sister of Laban the Syrian.

²¹ And Isaac entreated the Lord for his wife, because she was barren; and the Lord was entreated by 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.
