611. But in the days of the voice of the seventh angel, when he is about to sound.- That this signifies the last state of the church, and then revelation of Divine Truth, is evident from the signification of the days of the voice of the seventh angel, as denoting the last state of the church; for the progressive changes of the state of the church are described by the sounding of the seven angels, therefore the voice of the seventh angel signifies the last state; and from the signification of, when he is about to sound, as denoting revelation then of Divine Truth. That by sounding a trumpet or horn is signified the influx of Divine Truth, and its revelation, may be seen above (n. 502). That its revelation is here signified, is evident from the following part of this verse, where it is said, "And the mystery of God shall be consummated, as he hath declared in good tidings to his servants the prophets." This signifies that the prediction concerning the coming of the Lord shall then be fulfilled. With the coming of the Lord there is also revelation of Divine Truth.

Like most numbers in the Bible, "six" can have various meanings depending on context, but has a couple that are primary. When used in relation to time -- six days, six hours, six years, etc. -- six generally represents a state of labor, struggle and conflict, especially the conflict involved with spiritual growth. The six days of creation, for instance, represent the stages we go through in our lives, working toward the peaceful seventh day, in which our evil desires are removed from us and we can rest. In most other references, six represents all desires for good and all the true ideas that come from those desires for good -- or in the contrary sense, all evil and all the resulting false thinking.
