Genesis 26:18-21

Darby(i) 18 And 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. 19 And Isaac`s servants dug in the valley, and found there a well of springing water. 20 But 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. 21 And they dug another well, and they strove for that also; and he called the name of it Sitnah.
