Apocalypse Explained #673
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.)

162. TIME IN HEAVEN
In spite of the fact that there is a succession and progression of all things in heaven, as in the world, yet angels have no notion or idea of time and space, not even knowing at all what time and space are. Time in heaven will now be treated of, and space in its appropriate section.
