Genesis 26:18-21

JPS_ASV_Byz(i) 18 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. 19 And Isaac's servants digged in the valley, and found there a well of living water. 20 And 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. 21 And they digged another well, and they strove for that also. And he called the name of it Sitnah.
