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:

9314. 'And will act as adversary to your adversaries' means that He will turn away all evils from which falsities arise. This is clear from the meaning of 'acting as adversary', when it refers to Jehovah or the Lord, as turning away, dealt with immediately above in 9313; and from the meaning of 'adversaries' as evils from which falsities arise, since those evils in the spiritual sense are 'adversaries' opposed to forms of good from which truths spring. The reason why evils from which falsities arise are meant by 'adversaries' is that falsities arising from evil are meant by 'enemies'; for wherever falsity is the subject in the Word, so too is evil, even as when truth is the subject so too is good, see 683, 793, 801, 2173, 2516, 2712, 3132, 4138 (end), 5138, 5502, 6343, 7945, 8339. From this it is evident that one thing is meant by 'acting as enemy to enemies' and another thing by 'acting as adversary to adversaries', and that the latter is not a repetition that occurs simply to make the subject sound more lofty.
