Genesis 26:17-21

So Isaac departed from Abimelech’s domain and camped near the Wadi of Gerar, where he settled. Isaac reopened and restored the wells his father Abraham had originally dug—the wells the Philistines had stopped up after Abraham’s death. And Isaac gave these wells the same names that his father had given them. One day, when Isaac’s servants dug in the valley, they uncovered a spring-fed well. But the herdsmen of Gerar picked a fight with Isaac’s herdsmen, saying, “That’s our well!” So Isaac named the well Argument because of the sharp contention. They dug a second well, and it also caused a quarrel, so Isaac named that well Hostility.
