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.

5551. 'In sorrow to the grave' means without hope of a restoration to life. This is clear from the meaning of 'sorrow' here as without hope, for sorrow comes when no hope exists any longer; and from the meaning of 'the grave' as resurrection and regeneration, dealt with in 2916, 2917, 3256, 4621, and so a restoration - a restoration of the Church - to life. For if neither the internal represented by 'Joseph' is present within the Church, nor the intermediary represented by 'Benjamin', nor faith in the will, which is charity, represented by 'Simeon', no hope of its restoration to life exists any longer.

[2] It does indeed seem strange that 'the grave' means a restoration to life; but that strangeness is due to man's idea about the grave. He makes no distinction between the grave and death, nor even between the grave and the corpse lying in it. But angels in heaven cannot have any such idea about the grave; theirs is an entirely different one from man's, namely the idea of resurrection and restoration to life. For when a person's corpse is committed to the grave he himself is raised into the next life. When thinking about the grave therefore the angels have no idea of death, only of life and consequently of a restoration to life.
