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:

136. And hast not denied my faith. That this signifies constancy in truths is evident from the signification of not denying, when predicated of faith, as being to be constant, for he who is constant does not deny; and from the signification of faith, as being truths, because truth has reference to faith, and faith to truth. There are two things which constitute the spiritual life of man, love and faith. All good has reference to love, and all truth to faith; but the faith of man has only so much of truth as it derives from the good of love, because all truth is from good, for it is the form thereof, and all good is the being (esse) of truth; for good, when it is formed, so as to be evident to the mind and through the mind in speech, is called truth - therefore it is said, that good is the being (esse) of truth. (But concerning this subject more may be seen in The Doctrine of the New Jerusalem 11-27; likewise 28-35, 54-64, 108-122.)
