1020. That these things are meant becomes clear from the fact that everything put together as history from Genesis 1 down to Eber in Chapter 11 means something different from what appears in the letter, and from the consideration that the historical narratives there are purely made-up history customary among the most ancient people. When attesting the truth of some matter they would say that 'Jehovah said it'. Here however 'God' is used because the subject is the spiritual Church.

That this signifies what is clear and manifest is evident from the signification of trumpet, as being the Divine truth manifested and revealed out of heaven, concerning which see above (n. 55). The voice heard from heaven by those who are in the spirit is usually heard as a human voice; but the reason of its being heard as a trumpet speaking was that it was clearly and manifestly perceived by the angels; and that which is clearly and manifestly perceived by them falls loudly into the hearing of the spirit. This was the case with John in order to arouse his attention, and thence his sight, lest anything should be obscure to him. The same is meant by the voice of a trumpet also in other places, as Matthew 24:31; Zech. 9:14; Psalms 47:5; Apoc. 8:2, 7, 8, 13; 9:1, 13, 14; 10:7; 18:22, and elsewhere.
