Genesis 20:11-13

Complete Jewish Bible

¹¹ Avraham replied, “It was because I thought, ‘There could not possibly be any fear of God in this place, so they will kill me in order to get my wife.’ ¹² But she actually is also my sister, the daughter of my father but not the daughter of my mother, and so she became my wife. ¹³ When God had me leave my father’s house, I told her, ‘Do me this favor: wherever we go, say about me, “He is my brother.”’”
