Genesis 26:18-20

The Voice

¹⁸ Isaac had to re-dig all of the water wells that his father had installed because the Philistines had filled them in after Abraham’s death. He renamed them with the names his father had given them. ¹⁹ But when Isaac’s servants dug in the valley and found a new well of fresh water, ²⁰ the herders of Gerar began quarreling with Isaac’s herders.

So Isaac named this well Esek, which means “contention,” because of the arguments he had with the herders.
