Genesis 20:12-14

Amplified Bible

¹² 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. ¹³ 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.”’” ¹⁴ 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].
