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.

154. How the States of Angels in Heaven Change
By "the changes of angels' states," we mean their changes in regard to love and faith and therefore in regard to wisdom and intelligence - to the state of their life, that is. States are attributes of life and of matters that pertain to life; and since angelic life is a life of love and faith and thereby of wisdom and intelligence, states are attributes of these, and we talk about states of love and faith and states of wisdom and intelligence. Now we need to describe how these states change for angels.
