''To stop up wells,' as inGenesis 26:15, denotes to be unwilling to know truths, and to deny them, and so to obliterate them. In Genesis 21, 'wells' signify doctrines, both those disputed and not disputed. Without this significance digging wells and disputing about them would have been too trivial to be mentioned in the divine Word.
