Genesis 25 NASB
19 Now these are the records of the generations of Isaac, Abraham's son: Abraham became the father of Isaac; 20 and Isaac was forty years
old when he took Rebekah, the daughter of Bethuel the Aramean of Paddan-aram, the sister of Laban the Aramean, to be his wife. 21 Isaac prayed to the
Lord on behalf of his wife, because she was barren; and the Lord answered him and Rebekah his wife conceived. 22 But the children struggled together
within her; and she said, "If it is so, why then am I this way?" So she went to inquire of the Lord.
