Arcana Coelestia # 8500
8500. 'And it did not become putrid, and there was no worm in it' means that there was nothing foul within it, because in that way they acted from the Divine in making it their own. This is clear from the meaning of 'putrifying' as something foul and hellish, spoken of in reference to evil, dealt with above in 8482; and from the meaning of 'worm' too as something foul and hellish, but spoken of in reference to falsity, dealt with in 8481. The fact that such things are present in whatever is done from self, but heavenly and Divine qualities within whatever is done from the Lord, see 8478.
Arcana Coelestia # 8482
8482. 'And became putrid' means consequently something hellish. This is clear from the meaning of 'putrifying' as something foul and hellish. 'Putrifying' here is used in reference to evil and 'worm' to falsity, for when good becomes evil it is as when flesh or when bread putrifies. The falsity arising from that evil is like the worms produced there by what is putrid.
