Genesis 20:9-11
20:9 Abimelech summoned Abraham and said to him, “What have you done to us? What sin did I commit against you that would cause you to bring such great guilt on me and my kingdom? You have done things to me that should not be done!”
20:10 Then Abimelech asked Abraham, “What prompted you to do this thing?”
20:11 Abraham replied, “Because I thought, ‘Surely no one fears God in this place. They will kill me because of my wife.’
