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.
ADONAI appeared to him and said, "Don't go down into Egypt, but live where I tell you.
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 -
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.
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."
So Yitz'chak settled in G'rar.
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."
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.
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.'"
