Resurrection, the first
'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.

Arcana Coelestia #4499
4499. 'Each took his sword' means falsity and evil. This is clear from the meaning of 'a sword' as truth engaged in conflict and consequently the defence of truth, and in the contrary sense falsity engaged in conflict, and consequently the vastation of truth, dealt with in 2799. The reason why 'a sword' at this point also means evil is that Levi was implicated, who represented charity, and so good. When good is turned into evil it uses falsity from evil to fight with, in which case anything it does is evil.
