'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

7419. 'And it will then be lice' means that evils will rise up from them. This is clear from the meaning of 'lice' as evils. But what evils these are and where they originate becomes clear from the correspondence of evils with such parasites. They are primarily evils on the level of the senses or utterly external level of a person's mind. This correspondence arises from the fact that lice live on the outside of the skin, among the dirt there and under scaly skin. The sensory level in those who have come to possess a knowledge of matters of belief yet lead a life of evil is also like this. When that knowledge is taken away from them, as happens to such persons in the next life, they are then mentally thick and stupid. They have appeared before me on several occasions; they are foul and repulsive. Molestations by evils are meant by the bitings of those parasites. This meaning of 'lice' cannot be substantiated from other places in the Word, for they are mentioned again only in David, where he refers to what took place in Egypt, Psalms 105:31.
