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 #2789
2789. 'And Abraham lifted up his eyes and saw' means thought and insight received from the Divine. This is clear from the meaning of 'the eyes' as intelligence, dealt with in 2701, so that 'lifting up the eyes' means raising one's intelligence, thus thinking; and from the meaning of 'seeing' as receiving insight from the Divine, since this experience is used to refer to the Lord.
