Genesis 26:6-8 World English Bible (WEB)

6. Isaac lived in Gerar.

7. The men of the place asked him about his wife. He said, “She is my sister,” for he was afraid to say, “My wife”, lest, he thought, “the men of the place might kill me for Rebekah, because she is beautiful to look at.”

8. When he had been there a long time, Abimelech king of the Philistines looked out at a window, and saw, and, behold, Isaac was caressing Rebekah, his wife.
