Genesis 26:16

The man grew great, and grew more and more until he became very great.

He had possessions of flocks, possessions of herds, and a great household. The Philistines envied him.

Now all the wells which his father’s servants had dug in the days of Abraham his father, the Philistines had stopped, and filled with earth.

Isaac departed from there, encamped in the valley of Gerar, and lived there.

Isaac dug again the wells of water, which they had dug in the days of Abraham his father, for the Philistines had stopped them after the death of Abraham. He called their names after the names by which his father had called them.

Isaac’s servants dug in the valley, and found there a well of flowing water.
