Genesis 26:7-9

Revised Standard Version

⁷ When the men of the place asked him about his wife, he said, “She is my sister”; for he feared to say, “My wife,” thinking, “lest the men of the place should kill me for the sake of Rebekah”; because she was fair to look upon. ⁸ When he had been there a long time, Abim′elech king of the Philistines looked out of a window and saw Isaac fondling Rebekah his wife. ⁹ So Abim′elech called Isaac, and said, “Behold, she is your wife; how then could you say, ‘She is my sister’?” Isaac said to him, “Because I thought, ‘Lest I die because of her.’”
