Genesis 20:12-18 New King James Version (NKJV)

12. But indeed she is truly my sister. She is the daughter of my father, but not the daughter of my mother; and she became my wife.

13. And it came to pass, when God caused me to wander from my father’s house, that I said to her, ‘This is your kindness that you should do for me: in every place, wherever we go, say of me, “He is my brother.” ’ ”

14. Then Abimelech took sheep, oxen, and male and female servants, and gave them to Abraham; and he restored Sarah his wife to him.

15. And Abimelech said, “See, my land is before you; dwell where it pleases you.”

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.
