495. Verses 5, 6. And the angel took the censer, and filled it from the fire of the altar, and cast it unto the earth; and there were voices, and thunders, and lightnings, and an earthquake. And the seven angels having the seven trumpets prepared themselves to sound.

5. "And the angel took the censer, and filled it from the fire of the altar," signifies the conjunction of celestial love and spiritual love n. 496; "and cast it unto the earth," signifies influx into the lower parts, where those were who were to be separated and removed (n. 497); "and there were voices, and thunders, and lightnings," signifies reasoning from the disturbance of the affections and of the thoughts therefrom, respecting good and evil and respecting truth and falsity (n. 498); "and an earthquake," signifies changes of state of the church (n. 499).

6. "And the seven angels having the seven trumpets prepared themselves to sound," signifies changes in their order to arise from the influx out of heaven (n. 500).

488. As it were for half an hour, signifies a time corresponding to, or the delay before, the preparation of all things for undergoing the changes that follow. It is said "half an hour" because a "half" signifies as much as is correspondent and as much as is sufficient, and an "hour" signifies a delay. "Hour" is frequently mentioned in the Word, by which duration greater or less is meant, but the period of a certain hour is not thought of; and when a number is added, as when it is said the first, the second, the sixth, the tenth, or the twelfth hour, the duration of state is signified, and then also the quality of state according to the signification of the number added. (Of the signification of "hour" see above, n. 194; and that "half" signifies as much as is correspondent, and as much as is sufficient, see Arcana Coelestia 10255.)
