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 #8417
8417. 'And the people will go out' means the consequent life. This is clear from the meaning of 'going' as living or life, dealt with in 1293, 3335, 4882, 5493, 5605; and 'going out' here, that is, going to collect the manna, has a similar meaning. Regarding the meaning of 'going' as life, see also 8420.
