Genesis 26:8-10

Darby Translation

⁸ And it came to pass when he had been there some time, that Abimelech the king of the Philistines looked out of the window, and saw, and behold, Isaac was dallying with Rebecca his wife.

⁹ Then Abimelech called Isaac, and said, Behold, she is certainly thy wife; and how saidst thou, She is my sister? and Isaac said to him, Because I said, Lest I die on account of her.

¹⁰ And Abimelech said, What is this thou hast done to us? But a little and one of the people might have lain with thy wife, and thou wouldest have brought a trespass on us.
