40. 'Creeping things which the waters bring forth' means facts which belong to the external man, while 'birds' generally means rational concepts and also intellectual concepts, of which the latter belong to the internal man. That creeping things from the waters, or fish, mean facts is clear in Isaiah,

I came, and there was no man. By My rebuke I will dry up the sea, I will make the rivers a desert. Their fish will stink because there is no water and will die of thirst. I will clothe the heavens with darkness. Isaiah 50:2-3.

[2] This is plainer still in Ezekiel where the Lord describes the new temple, or new Church in general, and the member of the Church, or person who has been regenerated, for every regenerate person is a temple of the Lord,

The Lord Jehovih ¹ said to me, Those waters which will go out to the boundary eastwards will come towards the sea, having been directed into the sea, and the waters will be fresh. And it will be that every living creature which swarms will live, wherever the water of the rivers reaches, and there will be very many fish, for these waters are going there and will become fresh; and everything will live where the river goes. And it will be that fishermen from En-gedi to En-eglaim will stand beside it, with nets spread out. Its fish according to their kinds will be very many, like the fish of the great sea. Ezekiel 47:8-10.

'Fishermen from En-gedi to En-eglaim with their nets stretched out' means people who are to teach the natural man about the truths of faith.

[3] In the Prophets 'birds' invariably means rational concepts and intellectual concepts, as in Isaiah,

Calling a bird of prey from the east, a man of My counsel from a distant land. Isaiah 46:11.

In Jeremiah,

I looked, and behold there was no man, and all the birds of the air ² had fled. Jeremiah 4:25.

In Ezekiel,

I will plant the sprig of a lofty cedar, and it will bring forth a branch, and bear fruit, and it will become a noble cedar, and under it will dwell every bird of every sort, ³ in the shade of its branches they will dwell. Ezekiel 17:23.

And in Hosea, when the subject is a new Church, or regenerate person,

And I will make for them a covenant on that day, with the wild animals of the field, and with the birds of the air, ² and with things moving on the ground. Hosea 2:18.

Anyone may see that because the Lord 'is making a new covenant' with them, 'wild animal' is not used to mean a wild animal, nor 'bird' to mean a bird.

Footnotes:

4729. 'And let us say, An evil wild animal has devoured him' means a lie invented out of a life of evil desires. This is clear from the meaning of 'a wild animal' as affection or else evil desire, dealt with in 45, 46, for in the genuine sense 'a wild animal' means that which is living, 774, 841, 908, and therefore 'an evil wild animal' here means a life of evil desires. The fact that a lie is meant is self-evident; and this lie is connected with what has come immediately before about them casting that Divine truth away among falsities - a lie invented out of a life of evil desires. For falsity arises from three different sources, the first being the teaching of the Church, the second the illusions of the senses, and the third the life of evil desires. Falsity arising from the teaching of the Church occupies solely the understanding part of a person's mind, for he has been convinced since early childhood that such falsity is the truth, confirmations coming in by and by to strengthen that conviction. But falsity arising from the illusions of the senses has less impact on the understanding part, for people who are under the influence of falsity arising from the illusions of the senses receive little insight from their understanding because their thinking is founded on base ideas and on sensory impressions. Falsity arising from a life of evil desires however springs from the will itself, or what amounts to the same, from the heart, for a person desires that which he wills from the heart. This is the worst kind of falsity because it clings and is not rooted out except by means of a new life received from the Lord.

[2] As is well known, man has two inner mental powers - the understanding and the will. That which the understanding takes in and absorbs does not therefore pass over into the will, but that which the will takes in and absorbs does pass over into the understanding; for what is in a person's will occupies his thought also. Consequently when his desires lead him to will what is evil he is also thinking about it and confirming it. And when thoughts of evil have become confirmations of it they are called falsities arising from a life of evil desires. These falsities are seen by that person as truths, and once he has confirmed those falsities, truths are then seen by him as falsities, for he has now blocked off the light that flows from the Lord through heaven. But if he has not confirmed those falsities, truths which have been previously absorbed by his understanding stand in the way and prevent those falsities from being confirmed.
