Genesis 26:7-8

New International Version

⁷ When the men of that place asked him about his wife, he said, “She is my sister,^(A)” because he was afraid to say, “She is my wife.” He thought, “The men of this place might kill me on account of Rebekah, because she is beautiful.”

⁸ When Isaac had been there a long time, Abimelek king of the Philistines^(B) looked down from a window and saw Isaac caressing his wife Rebekah.
