3418. Verse 18. And Isaac returned, and digged again the wells of waters which they had digged in the days of Abraham his father; and the Philistines stopped them up after the death of Abraham; and he called their names after the names which his father called them. "And Isaac returned, and digged again the wells of waters which they had digged in the days of Abraham his father," signifies that the Lord opened those truths which were with the ancients; "and the Philistines stopped them up after the death of Abraham," signifies that they who were in the mere memory-knowledge of knowledges denied those truths; "and he called their names," signifies their quality; "after the names which his father called them," signifies significatives of truth.
