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.

9403. 'And Moses and Aaron went up, Nadab and Abihu' means the Word in its inward and outward senses, and teachings derived from both senses. This is clear from the representation of 'Moses and Aaron' as the Word in its inward and outward senses; and from the representation of 'Nadab and Abihu', Aaron's sons, as teachings derived from both senses, all of whom are dealt with above in 9374, 9375.
