Genesis 20:16-18 New King James Version (NKJV)

16. Then to Sarah he said, “Behold, I have given your brother a thousand pieces of silver; indeed this vindicates you before all who are with you and before everybody.” Thus she was rebuked.

17. So Abraham prayed to God; and God healed Abimelech, his wife, and his female servants. Then they bore children;

18. for the Lord had closed up all the wombs of the house of Abimelech because of Sarah, Abraham’s wife.
