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:

The relationship between men and women is deep and nuanced, and one entire book of the Writings -- Conjugial Love -- is devoted to the subject. So we can hardly offer a full explanation here. In a very general sense, though, the Writings say that men are creatures of intellect, driven by the love of growing wise; women, meanwhile are creations of affection, driven by the love of wisdom and the good that wisdom can do. They are formed this way to reflect the Lord's Divine Love and Divine Wisdom, and so that they can form marriages that reflect the unity of Divine Love and Divine Wisdom. Marking differences between men and women can be a touchy thing, but realistically it's easy to see that men tend to love acquiring knowledge whether it has any practical application or not. Many of them can spout out sports statistics or hold court on the workings of the internal combustion engine, even though it is knowledge they are not likely to ever use. They find such knowledge interesting for its own sake. It follows, then, that when the Bible speaks of men, the men represent facts, ideas, knowledge, truth, intellect and wisdom -- or in the negative sense falsity, twisted logic, and reasoning that is devoid of concern for others.
