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."

'Word,' as in Isaiah 9:8, signifies the doctrine of internal and external worship. 'Word,' as in Psalms 119:6-17, stands for doctrine in general.

'The Word,' as in Psalms 147:18, signifies divine good united with divine truth.

The whole Word is nothing but the doctrine of love towards the Lord, and love towards our neighbor, as in Matthew 22.
