58. Verse 30 And to every wild animal of the earth and to every bird of the air, ¹ and to everything creeping over the earth in which there is a living soul [I give] every plant for food; and it was so.

The natural food of this same [spiritual man] is being described here. His natural level is here meant by 'wild animal of the earth' and by 'bird of the air, to which 'the edible and green plant ² has been given for food'. Both kinds of food, natural and spiritual, are referred to in David as follows,

Jehovah causes the grass to grow for the beast, and the plant for man's service, that he may bring forth bread from the earth. Psalms 104:14.

Here 'beast' stands for both wild animals of the earth and birds of the air, ¹ both being mentioned in verses 11-12 of that Psalm.

Footnotes:

Fish represent knowledge. Fish laid upon the fire, as in John 21:9, represent the reformation of the natural man by the good of love, of which description were all the men of that time, in consequence of the complete vastation of the church. Fish signify sensual affections which are the ultimate affections of the natural man. Fish sometimes also represent people in common truth or conversely in external falsity. Broiled fish, as in Luke 24:42, signify the truth of good relating to the natural and sensual man, and honeycomb, the good of the same truth. To make as the fishes of the sea, signifies to make altogether sensual. Fish, as in Habakkuk 1:14-16, signify people in faith separate from charity.
