Genesis 20:11-13

11Abraham said, “Because I thought, surely there is no 1fear of God in this place, and 2they 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 3God caused me to wander from my father’s house, that I said to her, ‘This is 4the kindness which you will show to me: 5everywhere we go, 6say of me, “He is my brother.”’”
