Genesis 20:11-15

Abraham said, “Because I thought, ‘Surely there is no fear or reverence of God in this place, and they will kill me because of my wife.’ Besides, she actually is my [half] sister; she is the daughter of my father [Terah], but not of my mother; and she became my wife. When God caused me to wander from my father’s house, I said to her, ‘This kindness and loyalty you can show me: at every place we stop, say of me, “He is my brother.” ’ ” Then Abimelech took sheep and oxen and male and female slaves, and gave them to Abraham, and returned Sarah his wife to him [as God commanded]. So Abimelech said, “Behold, my land is before you; settle wherever you please.”
