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.

9756. 'The hangings shall be fifty cubits' means the quantity of truths needed for the purposes they have to serve. This is clear from the meaning of 'the hangings of the court' as truths such as they are in the lowest heaven, dealt with above in 9743; and from the meaning of 'fifty' as all belonging to one side, and also a sufficient amount. 'Fifty' is similar in meaning to 'five' (for what 'five' means, see 9604, 9689), and therefore also means the quantity needed for the purposes they have to serve, since this is a sufficient amount.
