7293. 'It will then be a water-serpent' means by the prospect that sheer illusions and resulting falsities will reign among them. This is clear from the meaning of 'a serpent' as the sensory and bodily level of mind, dealt with in 6949, and therefore illusions since that level of mind when separated from the rational level, that is, when not subordinate to it, is filled with illusions, to such an extent that it consists of scarcely anything else than illusions, see 6948, 6949. 'A water-serpent' is what is meant here; for in the original language the same word is used for this kind of serpent as that which is used to refer to a monster that is a very large fish of the sea; and 'a (sea-)monster' means factual knowledge in general.
When therefore falsities resulting from illusions are meant by 'the Egyptians', that word used in the original language denotes a serpent - a water-serpent since it can also be used to refer to the monster living in water and 'the water of Egypt' means falsities.
[2] The fact that Pharaoh or Egypt is called 'a monster' is clear in Ezekiel,
Speak and say, Thus said the Lord Jehovih, Behold, I am against you, Pharaoh king of Egypt, the great monster that lies in the midst of his rivers. Ezek 29:3.
In the same prophet,
Son of man, raise a lamentation over Pharaoh king of Egypt, and say to him, You have become like a young lion of the nations, you are like monsters in the seas, and you have come forth with your rivers; you have stirred up your rivers Ezek 32:2.
Here 'monster' means known facts in general which, being the product of what a person's senses tell him, are used to pervert matters of faith. The reason why 'monster' means factual knowledge in general is that 'a fish' means that knowledge in particular, 40, 991. And since known facts perverting the truths of faith are meant by 'monsters', reasonings based on illusions, which give rise to falsities, are also meant by the same word.
[3] The same things are meant by 'monsters' in David,
You broke up the sea by your strength; you broke the heads of the monsters upon the waters. Ps 74:13.
Much the same is also meant by 'leviathan' in Isaiah,
On that day Jehovah will make a visitation with His hard and great and strong sword upon Leviathan the full-length serpent,a and upon Leviathan the twisting serpent, and He will slay the monsters that are in the sea. Isa 27:1.
And in David,
You broke in pieces the heads of Leviathan; you gave him as food to the people, the Ziim. Ps 74:14.
In the good sense 'Leviathan' stands for reason based on truths, in Job 41:1-34; reason based on truths is the opposite of reasonings based on falsities.
[4] Since 'monsters' means reasonings that are based on illusions and pervert truths, 'water-serpents' - the word for which in the original language is the same as that used for 'monsters' - means the actual falsities resulting from illusions which give rise to reasonings and lead to perversions of the truth. Falsities are meant by such 'serpents' in the following places: In Isaiah,
The iim will reply in its palaces, and serpents in the delightful palaces. Isa 13:22.
In the same prophet,
Thorns will come up into its palaces, thistle and brier in its fortifications, so that it may be a dwelling-place of serpents, a courtyard for daughters of the owl. Isa 34: 13.
In the same prophet,
In the dwelling-place of serpents will his bed be, grass instead of reed and rush. Isa 35:7.
In Jeremiah,
I will make Jerusalem heaps of rubble, the dwelling-place of serpents. Jer 9:11.
In Malachi,
I have turned the mountains of Esau into a waste, and his inheritance into [a place] for the serpents of the wilderness. Mal 1:3.
In all these places 'serpents' stands for falsities on which reasonings are based.
[5] The same things are also meant by 'dragons', but 'dragons' are reasonings that spring from self-love and love of the world, thus from desires for what is evil, which pervert not only truths but forms of good as well. These reasonings are produced by people who in their hearts repudiate the truths and forms of the good of faith, but affirm them with their lips because of their intense desire to obtain dominance and gain. Thus such reasonings are also produced by those who render truths and forms of good profane. Both of these kinds of people are meant by 'the dragon, the serpent of old, who is called the devil and satan, who leads the whole world astray', Rev 12:9, and also by this same dragon which persecuted the woman who had given birth to a son who was caught up to God and to His throne, Rev 11:5, and which emitted water from its mouth like a river, to swallow up the woman, Rev 12:13, 15.
[6] The son to whom the woman had given birth is Divine Truth now revealed at the present day, 'the woman' being the Church. 'The dragon, the serpent' is those who are going to persecute it, and 'the water like a river which the dragon emitted' is falsities arising out of evil and the resulting reasonings which they are going to use in their endeavour to destroy the woman, that is, the Church. But the fact that they will not at all accomplish this is described by the statement that 'the earth helped the woman, and the earth opened its mouth and swallowed the river which the dragon emitted', Rev 12:16.
