Genesis 26:6-8

New Revised Standard Version Catholic Edition

⁶ So Isaac settled in Gerar. ⁷ When the men of the place asked him about his wife, he said, “She is my sister”; for he was afraid to say, “My wife,” thinking, “or else the men of the place might kill me for the sake of Rebekah, because she is attractive in appearance.” ⁸ When Isaac had been there a long time, King Abimelech of the Philistines looked out of a window and saw him fondling his wife Rebekah.
