Genesis 26:12-19

12Isaac planted crops in that land and the same year reaped a hundredfold, because the LORD blessed him. 13The man became rich, and his wealth continued to grow until he became very wealthy. 14He had so many flocks and herds and servants that the Philistines envied him.

15So all the wells that his father’s servants had dug in the time of his father Abraham, the Philistines stopped up, filling them with earth.

16Then Abimelek said to Isaac, “Move away from us; you have become too powerful for us.” 17So Isaac moved away from there and encamped in the Valley of Gerar, where he settled.

18Isaac reopened the wells that had been dug in the time of his father Abraham, which the Philistines had stopped up after Abraham died, and he gave them the same names his father had given them. 19Isaac’s servants dug in the valley and discovered a well of fresh water there.
