Genesis 26:12-18

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.” And Isaac departed from there and camped in the valley of Gerar, and settled there. Then Isaac dug again the wells of water which had been dug in the days of his father Abraham, for the Philistines had stopped them up after the death of Abraham; and he gave them the same names which his father had given them.
