3411. Verses 15-17. And all the wells that his father's servants digged in the days of Abraham his father, the Philistines stopped them up, and filled them with dust. And Abimelech said unto Isaac, Go away from us; for thou art much mightier than we. And Isaac departed thence, and encamped in the valley of Gerar, and dwelt there. "And all the wells that his father's servants digged in the days of Abraham his father, the Philistines stopped them up," signifies that they who were in the memory-knowledge of knowledges were not willing to know interior truths which are from the Divine, and thus obliterated them; "and filled them with dust," signifies by earthly things; "and Abimelech said unto Isaac," signifies the Lord's perception concerning this doctrine; "go away from us; for thou art much mightier than we," signifies that they could not endure those truths because of the Divine in them; "and Isaac departed thence," signifies that the Lord left interior doctrinal things; "and encamped in the valley of Gerar, and dwelt there," signifies that He betook Himself to lower rational things, that is, from interior appearances to exterior ones.
