Genesis 26:1-9

1 A famine came over the land, not the same as the first famine, which had taken place when Avraham was alive. Yitz'chak went to G'rar, to Avimelekh king of the P'lishtim.
2 ADONAI appeared to him and said, "Don't go down into Egypt, but live where I tell you.
3 Stay in this land, and I will be with you and bless you, because I will give all these lands to you and to your descendants. I will fulfill the oath which I swore to Avraham your father -
4 I will make your descendants as numerous as the stars in the sky, I will give all these lands to your descendants, and by your descendants all the nations of the earth will bless themselves.
5 All this is because Avraham heeded what I said and did what I told him to do -he followed my mitzvot, my regulations and my teachings."
6 So Yitz'chak settled in G'rar.
7 The men of the place asked him about his wife, and out of fear he said, "She is my sister." He thought, "If I tell them she's my wife, they might kill me in order to take Rivkah. After all, she is a beautiful woman."
8 But one day, after he had lived there a long time, Avimelekh king of the P'lishtim happened to be looking out of a window when he spotted Yitz'chak caressing Rivkah his wife.
9 Avimelekh summoned Yitz'chak and said, "So she is your wife, after all! How come you said, 'She is my sister'?" Yitz'chak responded, "Because I thought, 'I could get killed because of her.'"
