Genesis 20:14-18
20:14 So Abimelech gave sheep, cattle, and male and female servants to Abraham. He also gave his wife Sarah back to him.
20:15 Then Abimelech said, “Look, my land is before you; live wherever you please.”
20:16 To Sarah he said, “Look, I have given a thousand pieces of silver to your ‘brother.’ This is compensation for you so that you will stand vindicated before all who are with you.”
20:17 Abraham prayed to God, and God healed Abimelech, as well as his wife and female slaves so that they were able to have children.
20:18 For the Lord had caused infertility to strike every woman in the household of Abimelech because he took Sarah, Abraham’s wife.
