3418. Verse 18 And Isaac came back and dug again the wells of water which they had dug in the days of Abraham his father and which the Philistines had been stopping up after Abraham's death; and he called them names, according to the names which his father had called them.

'Isaac came back and dug again the wells of water which they had dug in the days of Abraham his father' means that the Lord disclosed the truths that had existed with the Ancients. 'And which the Philistines had been stopping up after Abraham's death' means that people who had no more than a knowledge of cognitions refused to recognize those truths. 'And he called them names' means the essential nature of them. 'Like the names which his father had called them' means meaningful signs of truth.
