9051. Eye for eye. That this signifies if they shall injure anything in the interior intellectual, is evident from the signification of “the eye,” as being the understanding, here the interior understanding, the life of which is the life of faith. Man has an exterior understanding, and an interior understanding. The exterior understanding is where the thought is that comes to perception; but the interior understanding is where the thought is that does not come to perception; nevertheless it does come to the perception of angels. This latter understanding is that which is enlightened by the Lord when man receives faith, for it is in the light of heaven, and in it is the spiritual life of man, which is not so manifest to him in the world, but is manifest in the other life, when the man becomes an angel among the angels in heaven. Meanwhile this life lies hidden within the thought of the exterior understanding, and produces therein a holy and reverent feeling for the Lord, for love and faith in Him, for the Word, and for all other things of the church. The reason why “the eye” denotes the understanding, is that the eye corresponds to the understanding, for the understanding sees by virtue of the light of heaven, but the eye by virtue of the light of the world. Those things which the former eye or understanding sees are spiritual, and the field of its view is the memory-knowledge in man’s memory. But the things which the external eye sees are earthly, and the field of its view is everything that appears in the world. That in the spiritual sense “the eye” denotes the understanding, and also faith, is because faith makes the life of the interior understanding (see n. 2701, 4403-4421, 4523-4534).

[2] He who does not know that the understanding is meant in the Word by “the eye,” cannot know what is signified by what the Lord spoke concerning the eye in the Evangelists, as by these words:

If thy right eye causeth thee to stumble, pluck it out; it is good for thee to enter into the kingdom of God with one eye, rather than having two eyes to be cast into the Gehenna of fire (Mark 9:47; Matthew 5:29).

Everyone knows that the eye is not to be plucked out, though it cause one to stumble, and that no one enters into the kingdom of God with one eye; but by “the right eye” is signified falsity of faith concerning the Lord, and this is what is to be plucked out. Again:

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

Neither in this passage is the eye meant by “eye,” but the understanding of the truth of faith. Hence the eye is called “the light of the body,” and it is said, “if the light that is in thee be darkness, how great is the darkness,” for in the spiritual sense “darkness” denotes falsities of faith (n. 1839, 1860, 4418, 4531, 7688, 7711).

[3] And again:

Why beholdest thou the mote that is in thy brother’s eye, but understandest not the beam that is in thine own eye? (Matthew 7:3-5).

“To behold a mote in the eye of a brother” denotes something erroneous in respect to the understanding of truth; and “the beam in one’s own eye” denotes the huge evil of falsity; for in the internal sense “wood” denotes good, and in the opposite sense evil (n. 643, 2784, 2812, 3720, 8354). Moreover in the other life good is represented by a beam; and therefore those who feign good in themselves seem to carry a beam, and thus go safely. Without this signification of “the eye,” and of “a beam,” what could be meant by “seeing a beam in the eye?” If it is not known that in the Word “the eye” denotes the understanding of truth, which is faith, neither can it be known what is involved in what the Lord did when He healed a blind man, that is, when “He spat on the ground and made clay of the spittle, and said unto him, Wash thee in the pool of Siloam” (John 9:6-7). As the Lord’s miracles, like all Divine miracles, involved those things which are of the Lord’s kingdom and church (n. 7337, 8364), so also does this.

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.
