Genesis 26:12-18

And Isaac sowed in that land and reaped in the same year a hundredfold. The LORD blessed him, and the man became rich, and gained more and more until he became very wealthy. He had possessions of flocks and herds and many servants, so that the Philistines envied him. (Now the Philistines had stopped and filled with earth all the wells that his father’s servants had dug in the days of Abraham his father.) And Abimelech said to Isaac, “Go away from us, for you are much mightier than we.” So Isaac departed from there and encamped in the Valley of Gerar and settled there. And Isaac dug again the wells of water that had been dug in the days of Abraham his father, which the Philistines had stopped after the death of Abraham. And he gave them the names that his father had given them.
