Genesis 26:17-22

17And Isaac departed thence, and pitched his camp in the valley of Gerar, and dwelt there.

18And Isaac dug again the wells of water that they had dug in the days of Abraham his father, and that the Philistines had stopped after the death of Abraham; and he called their names after the names by which his father had called them.

19And Isaac's servants dug in the valley, and found there a well of springing water.

20But the shepherds of Gerar strove with Isaac's shepherds, saying, The water is ours. And he called the name of the well Esek, because they had quarrelled with him.

21And they dug another well, and they strove for that also; and he called the name of it Sitnah.

22And he removed thence and dug another well; and they did not strive for that. And he called the name of it Rehoboth, and said, For now Jehovah has made room for us, and we shall be fruitful in the land.
