Genesis 26:18-25

And Isaac dug again the wells of water which they had dug in the days of Abraham his father, for the Philistines had stopped them up after the death of Abraham. He called them by the names which his father had called them. Also Isaac’s servants dug in the valley, and found a well of running water there. But the herdsmen of Gerar quarreled with Isaac’s herdsmen, saying, “The water is ours.” So he called the name of the well Esek, because they quarreled with him. Then they dug another well, and they quarreled over that one also. So he called its name Sitnah. And he moved from there and dug another well, and they did not quarrel over it. So he called its name Rehoboth, because he said, “For now the LORD has made room for us, and we shall be fruitful in the land.” Then he went up from there to Beersheba. And the LORD appeared to him the same night and said, “I am the God of your father Abraham; do not fear, for I am with you. I will bless you and multiply your descendants for My servant Abraham’s sake.” So he built an altar there and called on the name of the LORD, and he pitched his tent there; and there Isaac’s servants dug a well.
