Genesis 26:17

He had possessions of flocks, possessions of herds, and a great household. The Philistines envied him.

Now all the wells which his father’s servants had dug in the days of Abraham his father, the Philistines had stopped, and filled with earth.

Abimelech said to Isaac, “Go away from us, for you are much mightier than we.”

Isaac dug again the wells of water, which they had dug in the days of Abraham his father, for the Philistines had stopped them after the death of Abraham. He called their names after the names by which his father had called them.

Isaac’s servants dug in the valley, and found there a well of flowing water.

The herdsmen of Gerar argued with Isaac’s herdsmen, saying, “The water is ours.” So he called the name of the well Esek, because they contended with him.
