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 #8795
8795. 'Saying, Take care not to go up into the mountain' means that there must be no extension whatever to celestial communities which have the love of good. This is clear from the meaning of 'going up' as extending to the Divine as He exists in a higher heaven; and from the meaning of 'the mountain' as the good of love there, dealt with in 4210, 6435, 8327, 8758. The nature of all this is clear from the explanation immediately above in 8794.
