Genesis 26:18-22

Now Isaac again dug [and reopened] the wells of water which had been dug in the days of Abraham his father, because the Philistines had filled them up [with dirt] after the death of Abraham; and he gave the wells the same names that his father had given them. But when Isaac’s servants dug in the valley and found there a well of flowing [spring] water, the herdsmen of Gerar quarreled with Isaac’s herdsmen, saying, “The water is ours!” So Isaac named the well Esek (quarreling), because they quarreled with him. Then his servants dug another well, and they quarreled over that also, so Isaac named it Sitnah (enmity). He moved away from there and dug another well, and they did not quarrel over that one; so he named it Rehoboth (broad places), saying, “For now the LORD has made room for us, and we shall be prosperous in the land.”
