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.

438. They had tails like scorpions. (9:10) This symbolizes the Word's truths falsified, by which they induce a mental numbness.

A tail symbolizes the last extension of the head, because the brain extends through the spinal column into the tail. Consequently the head and the tail are united as their first and last elements. Consequently, when the head symbolizes a justifying and saving faith alone, the tail symbolizes in summary all its proofs, and as these are taken from the Word, it symbolizes the Word's truths falsified.

Everyone who assumes some principle of religion on the basis of on his own intelligence and puts it at the head of the rest, also takes proof passages from the Word and puts them at the tail, thus inducing a mental numbness in others and so doing them injury. That is why we are told that "they had tails like scorpions," and next, that "there were stings in their tails," and that "their power was to hurt men." For a scorpion symbolizes a persuasiveness that induces a numbness in the intellect (no. 425).

To be assured that the tail is an extension of the brain through the spinal column to its final point, ask any anatomist and he will tell you. Or look at a dog or some other fierce animal that has a tail, and if you treat it kindly and make yourself agreeable to it, you will see its stiffened back soften and its tail move in a corresponding manner. But on the other hand, if you annoy it, its backbone stiffens.

[2] The primary tenet of the intellect that is assumed as a principle is symbolized by the head, and its final expression by the tail, also in the following passages:

...He will cut off head and tail from Israel... The elder and honorable man is the head; but the prophet who teaches lies is the tail. (Isaiah 9:14-15)

There will not be any work for Egypt that the head or tail... may do. (Isaiah 19:15)

Nothing else is symbolized by the dragon's seven heads and the tail by which it drew a third of the stars of heaven and threw them to the earth, in Revelation 12:3-4; and also by the tails like serpents, having heads, with which they do harm, in verse 19 of this chapter.

Since the tail symbolizes the final element, and the final element embraces all the rest, therefore Jehovah said to Moses,

"...take (the serpent) by the tail." And he... caught it, and it became a rod... (Exodus 4:3-4)

The priests were also commanded therefore to remove the whole tail close to the backbone and to sacrifice it with the fat on the entrails, the kidneys, the intestines, and the liver (Leviticus 3:9-11; 8:25; 9:19, Exodus 29:22).

To be shown that the final element contains and embraces all the prior ones, see The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 38 65, and Angelic Wisdom Regarding Divine Love and Wisdom, nos. 209-216 217-222.
