Genesis 26:18-21
18 Isaac reopened the water wells that had been dug in the days of his father Abraham and that the Philistines had stopped up after Abraham died. He gave them the same names his father had given them.
19 Then Isaac’s slaves dug in the valley and found a well of spring(a) water there.
20 But the herdsmen of Gerar quarreled with Isaac’s herdsmen and said, “The water is ours!” So he named the well Quarrel(b) because they quarreled with him.(A)
21 Then they dug another well and quarreled over that one also, so he named it Hostility.(c)
