Genesis 26:3

1There was a famine in the land, in addition to the first famine that was in the days of Abraham. Isaac went to Abimelech king of the Philistines, to Gerar.

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

3Live 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.

4I 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,

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

6Isaac lived in Gerar.

7The 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.”
