Genesis 26:17-25

And Isaac departed thence, and encamped in the valley of Gerar, and dwelt there. And 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. And Isaac’s servants digged in the valley, and found there a well of springing water. And the herdsmen of Gerar strove with Isaac’s herdsmen, saying, The water is ours: and he called the name of the well Esek, because they contended with him. And they digged another well, and they strove for that also: and he called the name of it Sitnah. And 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 Jehovah hath made room for us, and we shall be fruitful in the land. And he went up from thence to Beer-sheba. And Jehovah appeared unto him the same night, and said, I am the God of Abraham thy father: fear not, for I am with thee, and will bless thee, and multiply thy seed for my servant Abraham’s sake. And he builded an altar there, and called upon the name of Jehovah, and pitched his tent there: and there Isaac’s servants digged a well.
