Genesis 20:16

12 And, in fact, she is my sister, the daughter of my father, but not the daughter of my mother; and she became my wife:

13 And when God sent me wandering from my father's house, I said to her, Let this be the sign of your love for me; wherever we go, say of me, He is my brother.

14 Then Abimelech gave to Abraham sheep and oxen and men-servants and women-servants, and gave him back his wife Sarah.

15 And Abimelech said, See, all my land is before you; take whatever place seems good to you.

16 And he said to Sarah, See, I have given to your brother a thousand bits of silver so that your wrong may be put right; now your honour is clear in the eyes of all.

17 Then Abraham made prayer to God, and God made Abimelech well again, and his wife and his women-servants, so that they had children.

18 For the Lord had kept all the women of the house of Abimelech from having children, because of Sarah, Abraham's wife.
