455. [And in their tails,] for their tails were like serpents, having heads, and with them they do harm. This symbolizes the reason, namely, that they are sensual and turned upside down, speaking truths with their mouths, but falsifying them by the premise which forms the chief tenet of their religion, and thus deceiving others.

The symbolism here is similar to that earlier in the case of the locusts (nos. 438, 439), but there we were told that they had tails like scorpions, and here tails like serpents. For the people described by locusts there speak and persuade using the Word, scholarship and learning, whereas the people described here employ arguments that consist only of appearances of truth and fallacies; and people who use these to speak harmoniously and seemingly wisely do indeed deceive others, but not to the same extent.

[2] Serpents in the Word symbolize sensual elements, which are the lowest constituents of a person's life, as described in no. 424 above. The reason is that all animals symbolize human affections. Consequently, in the spiritual world the affections of angels and spirits also look at a distance like animals, and merely sensual affections like serpents. That is because serpents slither along the ground and lick the dust, and sensual matters are the lowest in the intellect and in the will, being most closely connected with the world and being fed by its objects and delights, which affect only the physical senses of the body.

Harmful serpents, of which there are many kinds, symbolize sensual matters dependent on the evil affections that form the interior motivations of the mind in people who, owing to the falsities accompanying evil, are irrational. And harmless serpents symbolize sensual matters dependent on the good affections that form the interior motivations of the mind in people who, owing to the truths accompanying goodness, are wise.

[3] Sensual matters dependent on evil affections are symbolized by serpents in the following passages:

They shall lick the dust like a serpent. (Micah 7:17)

Dust shall be the serpent's food. (Isaiah 65:25)

(The serpent was told:) On your belly you shall go, and you shall eat dust all the days of your life. (Genesis 3:14)

The sensual level in a person is thus described, and because it communicates with hell, where the people are all sensual, it turns heavenly wisdom in spiritual matters into hellish insanity.

Do not rejoice, Philistia...; for out of the serpent's roots will come forth a viper, whose offspring will be a fiery flying serpent. (Isaiah 14:29)

They hatch a viper's eggs...; he who eats of its eggs dies, and when anyone squeezes them, a viper breaks out. (Isaiah 59:5)

Because the children of Israel wished to return to Egypt, they were bitten by serpents (Numbers 21:4-9). To return to Egypt means, symbolically, to go from being spiritual to being sensual. So we read,

(The) mercenaries (of Egypt)...are turned back... Its sound shall go like that of a serpent... (Jeremiah 46:21-22)

[4] Because Dan was the furthest out of the tribes and so symbolized the outmost component of the church, which is the sensual one subject to its interior ones, therefore this is said of it:

Dan shall be a serpent by the way... that will bite the horse's heels so that its rider falls backward. (Genesis 49:17)

A horse's heels symbolize the lowest constituents of the intellect, which are its sensual ones. To bite means, symbolically, to cling to them. The rider symbolizes the ignorance produced by them, by which it perverts truths. We are told, therefore, that the rider will fall backward.

Since sensual people are cunning and crafty like foxes, therefore the Lord says, "Be as wise as serpents" (Matthew 10:16). For a sensual person speaks and reasons on the basis of appearances and fallacies, and if he possesses a talent for arguing, he knows how to skillfully defend every falsity, including as well the heresy of faith alone; and yet he is so dim-sighted at seeing truth that almost no one could be more so.

9216. 'In which he may sleep' means resting on them. This is clear from the meaning of 'sleeping' as resting, in this instance on the external and sensory level, meant by 'clothing', 9212; for it says that it is clothing 'in which he may sleep'. How the explanation that more internal things find rest on the sensory level should be understood must be stated. The sensory level is the last and lowest of a person's life, as has been shown above. What is lowest contains all the more internal levels and is general to them all; for they terminate in it and accordingly rest on it. It is like the skin, for example, which is the outermost covering of the body. The body and all things in it terminate in the skin, because it contains them and they accordingly rest on the skin. In a similar way it is like the peritoneum within the body. Because it contains the abdominal organs, these rest on it and are also linked to it all round. Or equally it is like the pleura's relationship to the organs in the chest.

[2] A similar situation exists with all the things that compose a person's actual life, with those for instance that are connected with his understanding and those that are connected with his will. These too follow one another in order from more internal things to relatively external ones. The relatively external ones are factual knowledge together with its delights, while the outermost things are those of the senses, which are in contact with the world through sight, hearing, taste, smell, and touch. The more internal things rest on them since they terminate in them. These are the matters that are meant in the spiritual sense by 'the covering' or 'the clothing in which he may sleep'. The reason why things on the level of the senses are meant by 'the clothing' or 'the covering' lies in correspondences; for as stated above in 9212, spirits and angels appear dressed in garments in keeping with their truths of faith. Those governed by truths springing from good appear in shining ones, as for instance those at the Lord's tomb did, Luke 24:4; Matthew 28:3, and also in ones of fine, white linen, as for instance those referred to in Revelation 19:14 did; and others appear in garments of various colours.

[3] Furthermore it should be realized that all things without exception proceed in successive stages from their first or inmost level to their terminations on the last and lowest and rest on them. Each thing at a prior or more internal stage in order has its own connection with terminations on the lowest level. Therefore if things on the lowest level are dispelled those on interior levels are also scattered. This also explains why there are three heavens. The inmost or third heaven flows into the middle or second heaven; the middle or second heaven flows into the first or lowest heaven, which in turn flows into and resides with mankind. Consequently the human race constitutes the lowest level of order; in it heaven terminates and on it heaven rests. This being so, the Lord in His Divine [Love and Care] always provides for the presence among the human race of a Church in which truth revealed by God exists; such truth on our planet is the Word. By means of this a continuous link exists between the human race and the heavens. This is why every detail of the Word has within it an internal sense which exists for heaven's benefit and whose nature is such that it joins angels' minds to those of people on earth in so firm a bond that they act as one. All this goes to show yet again the nature of a situation in which interior things rest on those at the lowest level.
