Genesis 26:5

1 Now there was another famine in the land, subsequent to the one that had occurred in Abraham’s time. And Isaac went to Abimelech king of the Philistines at Gerar.

2 The LORD appeared to Isaac and said, “Do not go down to Egypt. Settle in the land where I tell you.

3 Stay in this land as a foreigner, and I will be with you and bless you. For I will give all these lands to you and your offspring, and I will confirm the oath that I swore to your father Abraham.

4 I will make your descendants as numerous as the stars in the sky, and I will give them all these lands, and through your offspring all nations of the earth will be blessed,

5 because Abraham listened to My voice and kept My charge, My commandments, My statutes, and My laws.”

6 So Isaac settled in Gerar.

7 But when the men of that place asked about his wife, he said, “She is my sister.” For he was afraid to say, “She is my wife,” since he thought to himself, “The men of this place will kill me on account of Rebekah, because she is so beautiful.”

8 When Isaac had been there a long time, Abimelech king of the Philistines looked down from the window and was surprised to see Isaac caressing his wife Rebekah.

9 Abimelech sent for Isaac and said, “So she is really your wife! How could you say, ‘She is my sister’?” Isaac replied, “Because I thought I might die on account of her.”
