Genesis 26:6-16

6 So Isaac settled in Gerar.
7 When the men of the place asked him about his wife, he said, "She is my sister"; for he was afraid to say, "My wife," thinking, "or else the men of the place might kill me for the sake of Rebekah, because she is attractive in appearance."
8 When Isaac had been there a long time, King Abimelech of the Philistines looked out of a window and saw him fondling his wife Rebekah.
9 So Abimelech called for Isaac, and said, "So she is your wife! Why then did you say, "She is my sister'?" Isaac said to him, "Because I thought I might die because of her."
10 Abimelech said, "What is this you have done to us? One of the people might easily have lain with your wife, and you would have brought guilt upon us."
11 So Abimelech warned all the people, saying, "Whoever touches this man or his wife shall be put to death."
12 Isaac sowed seed in that land, and in the same year reaped a hundredfold. The Lord blessed him,
13 and the man became rich; he prospered more and more until he became very wealthy.
14 He had possessions of flocks and herds, and a great household, so that the Philistines envied him.
15 (Now the Philistines had stopped up and filled with earth all the wells that his father's servants had dug in the days of his father Abraham.)
16 And Abimelech said to Isaac, "Go away from us; you have become too powerful for us."
