Genesis 20:11-13

New Revised Standard Version, Anglicised Catholic Edition

¹¹ Abraham said, ‘I did it because I thought, There is no fear of God at all in this place, and they will kill me because of my wife. ¹² Besides, she is indeed my sister, the daughter of my father but not the daughter of my mother; and she became my wife. ¹³ And when God caused me to wander from my father’s house, I said to her, “This is the kindness you must do me: at every place to which we come, say of me, He is my brother.”’
