Genesis 26:18-21

Leeser(i) 18 And Isaac dug again the wells of water, which they had dug in the days of Abraham his father, and which the Philistines had stopped after the death of Abraham; and he called their names after the names by which his father had called them. 19 And the servants of Isaac dug in the valley, and found there a well of springing water. 20 And the herdmen of Gerar did strive with Isaac’s herdmen, saying, The water is ours: and he called the name of the well Essek; because they strove with him. 21 And they dug another well, and they strove for that also: and he called the name of it Sitnah.
