Genesis 26:12-16

Now Isaac sowed in that land and reaped in the same year a hundredfold. And the LORD blessed him, and the man became rich, and continued to grow richer until he became very wealthy; for he had possessions of flocks and herds and a great household, so that the Philistines envied him. Now all the wells which his father’s servants had dug in the days of Abraham his father, the Philistines stopped up by filling them with earth. Then Abimelech said to Isaac, “Go away from us, for you are too powerful for us.”
