Genesis 26:17-18 NASB1995
And Isaac departed from there and camped in the valley of Gerar, and settled there.
Then Isaac dug again the wells of water which had been dug in the days of his father Abraham, for the Philistines had stopped them up after the death of Abraham; and he gave them the same names which his father had given them.
