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 #6868
6868. 'And that I should lead the children of Israel out' means and so deliver those who belonged to the spiritual Church. This is clear from the meaning of 'leading out' as delivering, as above in 6865; and from the representation of 'the children of Israel' as those belonging to the spiritual Church, dealt with in 6637, 6862, 6865.
