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:

Morning comes with the rising of the sun, and the sun -- which gives life to the earth with its warmth and light -- represents the Lord in His divinity, bringing spiritual life through love and wisdom. Thus, the morning represents the coming of the Lord into our lives, and all the things that flow from it: the love, joy and enlightenment He brings; the peace and tranquility of passing the spiritual obscurity of night; the anticipation of the learning and usefulness of a new day; and the awareness of The Lord's renewed presence.
