670. That 'living creature' ¹ means things of the understanding, and 'all flesh' those of the will, becomes clear from what has been stated already, and also from what follows. In the Word 'living creature' means all animal life in general, as in Genesis 1:10, 21, 24; 2:19. Here however, because the phrase 'all flesh' is added immediately after, it means things which belong to the understanding, for the reason given already, that the regeneration of the member of this Church had to begin in the things of the understanding. This also is why in the next verse 'birds' are mentioned first, which mean things of the understanding or the rational, and 'beasts', which are those of the will, second. 'Flesh' in particular means bodily-mindedness which is a feature of the will.

5. Verse 1. The revelation of Jesus Christ, signifies predictions from the Lord respecting the last times of the church. This is evident from the signification of "revelation," as being predictions; and since these are from the Lord alone, it is said, "the revelation of Jesus Christ." The revelation, or predictions, are respecting the last times of the church, since those times are especially treated of. It may be supposed that in Revelation the successive states of the church from beginning to end are treated of; these, however, are not there treated of, but only the state of heaven and of the church near the end, when the Last Judgment takes place, thus the last times. The successive states of the church were foretold by the Lord Himself in Matthew 24, Matthew 25; and also in Mark 13; yet what is there given is written in the Divine prophetic style, that is, by means of correspondences; consequently it is of such a character that it can only be revealed and made evident by the internal or spiritual sense. (It has therefore been granted me from the Lord to unfold these things in the Arcana Coelestia, at the beginning of chapters Genesis 26 to Genesis 40 of Genesis; which explanations may be seen in their order, in the following places: n.
