Genesis 26:5

2 The LORD appeared to him, and said, “Don’t go down into Egypt. Live in the land I will tell you about.

3 Live in this land, and I will be with you, and will bless you. For I will give to you, and to your offspring, all these lands, and I will establish the oath which I swore to Abraham your father.

4 I will multiply your offspring as the stars of the sky, and will give all these lands to your offspring. In your offspring all the nations of the earth will be blessed,

5 because Abraham obeyed my voice, and kept my requirements, my commandments, my statutes, and my laws.”

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.
