Genesis 26:15-18

15So the Philistines filled up all of Isaac’s wells with dirt. These were the wells that had been dug by the servants of his father, Abraham.

16Finally, Abimelech ordered Isaac to leave the country. “Go somewhere else,” he said, “for you have become too powerful for us.”

17So Isaac moved away to the Gerar Valley, where he set up their tents and settled down.

18He reopened the wells his father had dug, which the Philistines had filled in after Abraham’s death. Isaac also restored the names Abraham had given them.
