Arcana Coelestia #4499
4499. Took each his sword. That this signifies falsity and evil, is evident from the signification of a “sword,” as being truth combating, and hence the defence of truth; and in the opposite sense, falsity combating, and hence the vastation of truth (see n. 2799). That “sword” here signifies evil also, is because Leviticus also was involved, by whom charity, thus good, was represented; and when this becomes evil it combats by falsity from evil, and what it then does is evil.
Isaiah 51:19-20
19
These two things have happened to you. Who will bemoan you? Desolation and destruction, and the famine and the sword; how shall I comfort you?
20
Your sons have fainted, they lie at the head of all the streets, as an antelope in a net; they are full of the wrath of Yahweh, the rebuke of your God.
