A long time before this, when Isaac’s father Abraham was alive, Abraham and his workers dug lots of water-holes in that place, and Abraham gave all those water-holes names. But then, after Abraham died, the Philistia people filled up all those water-holes with dirt, so nobody could get water from them. Now, when Isaac moved there, he got his workers to take the dirt out of those water-holes, so that everybody could get water again. And Isaac gave those water-holes the same names that Abraham gave them a long time before.
