5217. And the thin ears swallowed up the seven fat and full ears. That this signifies that the memory-knowledges of no use banished the good memory-knowledges, is evident from the signification of the "thin ears," as being memory-knowledges of no use (of which above, n. 5214); and from the signification of the "fat and full ears," as being memory-knowledges into which the things of faith and charity could be applied (n. 5213), consequently good memory-knowledges; and from the signification of "swallowing up," as being to banish-the same as "eating up," which is said above of the kine (n. 5206). (That the good memory-knowledges were banished by those of no use, or that truths were banished by falsities, may be seen above, n. 5207.)
So also is it in the spiritual world: where falsities are, truths cannot subsist; and on the other hand, where truths are, falsities cannot subsist. The one banishes the other, for they are opposites. The reason is that falsities are from hell and truths are from heaven. It sometimes appears as if falsities and truths are in one subject; but these are not falsities that are opposite to the truths in him, but are those which are associated by applications. The subject in whom truths, and at the same time falsities which are opposite to them, subsist, is called "lukewarm;" and the subject in whom falsities and truths are mingled is called "profane."
