Genesis 26:17-22

17Then Isaac departed from there and pitched his tent in the Valley of Gerar, and dwelt there.

18And 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.

19Also Isaac’s servants dug in the valley, and found a well of running water there.

20But 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.

21Then they dug another well, and they quarreled over that one also. So he called its name Sitnah.

22And 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.”
