Apocalypse 1: 10. “And I heard behind me a great voice as of a trumpet, signifies the manifest perception of Divine truth revealed from heaven. A great voice, when it is heard from heaven, signifies the Divine truth, treated of in what follows. It was heard as a trumpet, because, when the Divine truth passes down from heaven, it is sometimes so heard by the angels of the ultimate heaven, and is then manifestly perceived. It is hence that by a voice as of a trumpet manifest perception is signified. The signification of a trumpet will be further treated of below. That a great voice, when heard from heaven, signifies the Divine truth, is manifest from these passages: The voice of Jehovah is upon the waters; the voice of Jehovah is in power; the voice of Jehovah is with honor: the voice of Jehovah is breaking the cedars: the voice of Jehovah falleth as a flame of fire: the voice of Jehovah maketh the wilderness to tremble: the voice of Jehovah maketh the hinds to calve (Ps. xxix. 3-9).
