'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.

673. Verse 13. And in that hour, signifies during that state. This is evident from the signification of "hour," as being state, so here that state when "the two witnesses went up into heaven, and their enemies beheld them." "Hour" signifies state, because in the Word times and all expressions pertaining to time, like "hours," "days," "weeks," "months," "years," "ages," as also "morning," "noon," "evening," "night," likewise "spring," "summer," "autumn," and "winter," signify states of life. (That times have this signification has been illustrated and shown in the work on Heaven and Hell 162-169, where Time in Heaven is treated of; also above, n. 571, 610, 664; and that "hour" signifies any duration of state, greater or less, thus time and state, see above, n. 194; and that the number adjoined defines what is the quality of the state, n. 488.)
