9052. Tooth for tooth. That this signifies if anything in the exterior intellectual, is evident from the signification of “a tooth,” as being the exterior intellectual, and therefore natural truth, for this makes the life of this understanding. That “the teeth” have this signification is because they grind like a mill, and thus prepare, the food which is to nourish the body; here the food which is to nourish the soul. The food which nourishes the soul is intelligence and wisdom. This is first received, ground, and prepared by means of the knowledges of truth and good in the natural. (That it is intelligence and wisdom which is called “spiritual and celestial food,” see n. 56-58, 680, 1480, 4792, 5147, 5293, 5340, 5342, 5576, 5579, 5915, 8562, 9003.) From this it is plain whence it is that “the teeth” signify the exterior understanding. What the exterior understanding is can be seen from what was shown just above (n. 9051) concerning the interior understanding.

[2] That “the teeth” signify natural truth, which belongs to the exterior understanding, and in the opposite sense the falsity which destroys this truth, is evident from the following passages in the Word. That they signify natural truth, in Moses:

His eyes shall be redder than wine, and his teeth whiter than milk (Genesis 49:12).

Here also both “eyes” and “teeth” are mentioned together. The subject treated of is Judah, by whom is meant the Lord as to the Divine celestial (n. 6363); “the eyes” signify the Divine intellectual of the the Lord, (n. 6379); and “the teeth,” His Divine natural (n. 6380), thus also the Divine truth in the natural.

[3] In Amos:

I have given you emptiness of teeth in all your cities, and lack of bread in all your places (Amos. 4:6).

“Emptiness of teeth” denotes scarcity of truth; and “lack of bread,” scarcity of good. From all this it is evident what is meant by the “gnashing of teeth” among those who are in hell (Matthew 8:12; 13:42, 50; 22:13; 25:30; Luke 13:28), namely, the collision of falsities with the truths of faith. For as before said, “the teeth,” in the opposite sense, signify the falsity which destroys truth; as in David:

Arise, O Jehovah; save me, O my God; for Thou wilt smite all mine enemies on the jaw; Thou wilt break the teeth of the wicked (Psalms 3:7).

“To break the teeth of the wicked” denotes to break the falsities by which they destroy truths. In the same:

As to my soul I lie in the midst of lions, their teeth are spears and arrows, and their tongue a sharp sword (Psalms 57:4).

“The teeth of lions” denote the falsities that destroy truths; “lions,” falsities from evil in their power (n. 6367, 6369).

[4] In the same:

Destroy their teeth, O God, in their mouth; turn aside the grinders of the young lions (Psalms 58:6).

In Joel:

A nation is come up upon My land, strong, and without number; his teeth are the teeth of a lion, and he hath the grinders of a great lion. He hath reduced My vine to a waste; and My fig-tree into froth (Joel 1:6-7).

“Teeth” and “grinders” denote the falsities that destroy the truths of the church; a “vine” denotes the spiritual church (n. 1069, 5113, 6376); and a “fig-tree” its natural good (n. 217, 4231, 5113). That “teeth” have this signification is plain also from the fact that they are attributed to a nation which will lay waste.

In John:

The shapes of the locusts were like unto horses prepared for war; they had hair as the hair of women, and their teeth were as the teeth of lions (John 9:7-8).

“Locusts” denote those who are in external falsities (n. 7643), from which it is also evident that “teeth” denote falsities that destroy truths.

2701. God opened her eyes. That this signifies intelligence, is evident from the signification of “opening” and of “God opening,” and also of “eyes” as being to give intelligence (that “eyes” signify the understanding may be seen above, n. 212, in like manner as “sight” or “seeing,” n. 2150, 2325). It is said that “God opens the eyes” when He opens the interior sight or understanding; which is effected by an influx into man’s rational, or rather into the spiritual of his rational. This is done by the way of the soul, or the internal way, unknown to the man. This influx is his state of enlightenment, in which the truths which he hears or reads are confirmed to him by a kind of perception interiorly within his intellectual. This the man believes to be innate in him, and to proceed from his own intellectual faculty; but in this he is very much mistaken; for it is an influx through heaven from the Lord into what is obscure, fallacious, and seeming with the man, which by means of the good therein causes the things which he believes to be similar to truth. But they only who are spiritual are blessed with enlightenment in the spiritual things of faith. It is this which is signified by “God opening the eyes.”

[2] That the “eye” signifies the understanding is because the sight of the body corresponds to the sight of its spirit, which is the understanding; and because it corresponds, in the Word the understanding is signified by the “eye” in almost every place where it is mentioned, even where it is believed to be otherwise; as where the Lord says in Matthew:

The light of the body is the eye; if therefore thine eye be single, thy whole body shall be full of light; but if thine eye be evil, thy whole body shall be full of darkness; if therefore the light that is in thee be darkness, how great is that darkness (Matthew 6:22-23; Luke 11:34).

Here the “eye” is the understanding, the spiritual of which is faith, as also is evident from the explication: “if therefore the light that is in thee be darkness, how great is that darkness.”

So too in the same:

If thy right eye causeth thee to stumble, pluck it out, and cast it from thee (Matthew 5:29; 18:9).

The “left eye” is the intellectual, but the “right eye” is its affection: that the right eye is to be plucked out means that the affection is to be subdued if it causes stumbling.

[3] In the same:

Blessed are your eyes, for they see, and your ears, for they hear (Matthew 13:16);

and in Luke:

Jesus said to the disciples, Blessed are the eyes which see the thing which ye see (Luke 10:23).

Here by the “eyes which see,” intelligence and faith are signified; for their seeing the Lord, and also His miracles and works, did not make them blessed; but comprehending them with the understanding and having faith, which is “seeing with the eyes;” and obeying, which is “hearing with the ears.” That to “see with the eyes” is to understand, and also to have faith, may be seen above (n. 897, 2325) for the understanding is the spiritual of the sight, and faith is the spiritual of the understanding. The sight of the eye is from the light of the world, but the sight of faith is from the light of heaven. Hence it is common to speak of seeing with the understanding, and of seeing by faith. (That to “hear with the ear” is to obey, may be seen above, n. 2542)

[4] Also in Mark:

Jesus said to the disciples, Do ye not yet perceive, neither understand? Have ye your heart yet hardened? Having eyes see ye not? And having ears hear ye not? (Mark 8:17-18); where it is manifest that not to be willing to understand and not to believe, is to “have eyes and not see.”

In Luke:

Jesus said of the city, If thou hadst known the things that belong unto thy peace; but now it is hid from thine eyes (Luke 19:41-42).

And in Mark:

This is the Lord’s doing, and it is marvelous in our eyes (Mark 12:11); where to be “hid from the eyes,” and to be “marvelous in the eyes,” means to be so to the understanding, as is known to everyone from the signification of the eye even in the common use of language.
