Genesis 20:8-13

8Abimelech got up early the next morning and quickly called all his servants together. When he told them what had happened, his men were terrified.

9Then Abimelech called for Abraham. “What have you done to us?” he demanded. “What crime have I committed that deserves treatment like this, making me and my kingdom guilty of this great sin? No one should ever do what you have done!

10Whatever possessed you to do such a thing?”

11Abraham replied, “I thought, ‘This is a godless place. They will want my wife and will kill me to get her.’

12And she really is my sister, for we both have the same father, but different mothers. And I married her.

13When God called me to leave my father’s home and to travel from place to place, I told her, ‘Do me a favor. Wherever we go, tell the people that I am your brother.’”
