Genesis 26:16-20
English Standard Version
17So Isaac departed from there and encamped in the Valley of Gerar and settled there.
18And 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.
19But when Isaac 's servants dug in the valley and found there a well of spring water,
20the herdsmen of Gerar quarreled with Isaac 's herdsmen, saying, "The water is ours." So he called the name of the well Esek, because they contended with him.
