'Locusts' signify falsities in the extremes, which consume the truths and goods of the church in a person. 'The locusts' which John the Baptist ate signify truths of a most common or general nature.

684. CONCERNING THE SOCIETIES WHICH CONSTITUTE HEAVEN

There are three heavens: the First is the abode of good spirits, the Second of angelic spirits, and the Third of angels. And one heaven is more interior and pure than another, so that they are most distinct. Each heaven, the first, the second, and the third, is distinguished into innumerable societies; and each society consists of many individuals, who by their harmony and unanimity constitute as it were one person; and all the societies together are as one man. The societies are distinct from one another according to the differences of mutual love, and of faith in the Lord. These differences are so innumerable that not even the most universal genera of them can be computed; and there is not the least of difference that is not disposed in most perfect order, so as to conspire most harmoniously to a common unity, and the common unity to unanimity of individuals, and thereby to the happiness of all from each, and of each from all. Each angel and each society is therefore an image of the universal heaven, and is as it were a little heaven.
