599. Verse 2. And he had in his hand a little book opened, signifies the Word laid open. This is evident from the signification of "a little book opened," as being the Word laid open. It can be seen that this is what is meant by "the little book opened," since "the strong angel coming down out of heaven, who had in his hand a little book," represented the Lord as to the Word, and in fact, as to its ultimate sense, which is called the sense of the letter (See above, n. 593); and because the Word was laid open both to angels and men it is said "a little book opened."

'Silence' has various meanings. In general, it signifies everything which causes it, including astonishment, which has a special cause in Revelation 8:1.
