Genesis 20:14

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

13When God caused me to wander from my father’s house, I said to her, ‘This is your kindness which you shall show to me. Everywhere that we go, say of me, “He is my brother.”’”

14Abimelech took sheep and cattle, male servants and female servants, and gave them to Abraham, and restored Sarah, his wife, to him.

15Abimelech said, “Behold, my land is before you. Dwell where it pleases you.”

16To Sarah he said, “Behold, I have given your brother a thousand pieces of silver. Behold, it is for you a covering of the eyes to all that are with you. In front of all you are vindicated.”
