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:

9431. 'Six days' means when passing through the state of truth. This is clear from the meaning of 'six days' as a state of labour and conflict, dealt with in 737, 8510, 8888, 8975. It is a state of truth because a person who is being regenerated by the Lord experiences two states, the first of which is called the state of truth and the second the state of good. The reason why the first state is called the state of truth is that during it the person is being brought by means of truth towards good; and the reason why the second state is called the state of good is that the person, when governed by good, has been brought to it. Also, while the person is in the state of truth he is outside heaven; but when governed by good he is in heaven, and has accordingly been brought to the Lord. Furthermore while the person is passing through the first state or the state of truth he experiences labour and conflict, since he undergoes temptations then; but when he is in the second state or the state of good he experiences rest and the serenity which peace brings. The former state is what has been represented in the Word by the six days which come before a seventh, whereas the latter state is what has been represented by the seventh day or the sabbath, see 8890, 8893, 9274. Regarding these two states with the person who is being regenerated, which are called the state of truth and the state of good, see what has already been shown extensively in 7923, 7992, 8505, 8506, 8510, 8513, 8516, 8539, 8643, 8648, 8658, 8685, 8690, 8701, 8722, 8772, 9139, 9224, 9227, 9230, 9274.
