Arcana Coelestia #670
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.

Arcana Coelestia #5833
5833. 'And now, when I come to your servant my father' means the good of the Church corresponding to the spiritual good which is that of the internal Church. This is clear from the representation of Judah, who says this about himself, as the good of the Church, dealt with in 5583, 5603, 5782, and from the representation of Israel, who is his 'father' here, as spiritual good, dealt with in 5807, 5812, 5813, 5817, 5819, 5825. The good of the Church that 'Judah' represents is the good of the external Church, whereas the spiritual good that 'Israel' represents is the good of the internal Church, 4286. For every Church of the Lord's is both internal and external, and features of the external Church correspond to features of the internal Church, so that the good of the Church which is 'Judah' corresponds to spiritual good which is 'Israel'.
