Genesis 20:8-13

⁸So Abimelech got up early in the morning and called all his servants, and told all these things in their presence; and the people were greatly frightened. ⁹Then Abimelech called Abraham and said to him, “What have you done to us? And how have I sinned against you, that you have brought on me and on my kingdom a great sin? You have done to me things that ought not to be done.” ¹⁰And Abimelech said to Abraham, “What have you encountered, that you have done this thing?” ¹¹Abraham said, “Because I thought, surely there is no fear of God in this place, and they will kill me because of my wife. ¹²Besides, she actually is my sister, the daughter of my father, but not the daughter of my mother; and she became my wife; ¹³and it came about, when God caused me to wander from my father’s house, that I said to her, ‘This is the kindness which you will show to me: everywhere we go, say of me, “He is my brother.” ’ ”
