Genesis 20:8-13

Abimelech was up first thing in the morning. He called all his house servants together and told them the whole story. They were shocked. Then Abimelech called in Abraham and said, “What have you done to us? What have I ever done to you that you would bring on me and my kingdom this huge offense? What you’ve done to me ought never to have been done.” Abimelech went on to Abraham, “Whatever were you thinking of when you did this thing?” Abraham said, “I just assumed that there was no fear of God in this place and that they’d kill me to get my wife. Besides, the truth is that she is my half sister; she’s my father’s daughter but not my mother’s. When God sent me out as a wanderer from my father’s home, I told her, ‘Do me a favor; wherever we go, tell people that I’m your brother.’”
