Genesis 26:18-23

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

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

20And the herdmen of Gerar strove with Isaac’s herdmen, saying, The water is ours: and he called the name of the well Esek; because they contended with him.

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

22And he removed from thence, and digged another well; and for that they strove not: and he called the name of it Rehoboth; and he said, For now the LORD hath made room for us, and we shall be fruitful in the land.

23And he went up from thence to Beer-sheba.
