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:

1831. 'And he laid each part opposite the other' means a parallelism and correspondence as regards celestial things. This becomes clear from the fact that the parts on one side mean the Church and those on the other the Lord. And when these are set in their proper places opposite each other, nothing else is meant than parallelism and correspondence. And because the heifer, the she-goat, and the ram, which mean celestial things, as stated just above at verse 9, were cut in half as described and laid in their proper places, it is clear that there is a parallelism and correspondence as regards celestial things. As regards spiritual things however, which will be dealt with shortly, the situation is different. As often stated, celestial things are all those that have to do with love to the Lord and love towards the neighbour. It is the Lord who imparts love and charity, the Church that receives; and that which unites is conscience, which has love and charity implanted within it. Consequently the space in between the parts means those things present in man which are called perception, internal dictate, and conscience. The things that exist above that perception, dictate, and conscience are the Lord's, those that are below reside in man. Thus because these things above and those below look towards one another, a parallelism is said to exist; and because they correspond to one another, as active and passive, a correspondence is said to exist.
