9051. 'Eye for eye' means if anything is injured by them in the inner part of the understanding. This is clear from the meaning of 'the eye' as the understanding, in this instance the inner part of it, the life of which is the life of faith. A person's understanding has an outer part and an inner part The outer part of his understanding is where thought that enters his awareness is, whereas the inner part is where thought that does not enter his awareness is, though it enters that of the angels. This part of the understanding is what the Lord enlightens when a person receives faith, for it exists in the light of heaven and holds within it a person's spiritual life. This is not made plainly evident to the person while in the world, but it is made so to that person in the next life when he becomes an angel among angels in heaven. In the meanwhile that life lies hidden within the thought belonging to the outer part of the understanding, producing there the holiness and reverence for the Lord, for love and faith in Him, for the Word, and for everything else that is the Church's. The reason why 'the eye' means the understanding is that the eye corresponds to the understanding; for the understanding sees in the light of heaven, but the eye sees in the light of the world. The things that the former eye, that is, the understanding, sees are spiritual, and its field of vision is the factual knowledge contained in the person's memory. But the things which the physical eye sees are earthly, and its field of vision consists in every object that appears in the world. Regarding 'the eye', that in the spiritual sense it means the understanding, and also faith since faith composes the life of the inner part of the understanding, see 2701, 4403-4421, 4523-4534.

[2] Anyone who does not know that 'the eye' is used in the Word to mean the understanding cannot know what the meaning is of the things which the Lord spoke concerning the eye in the Gospels, first of all these,

If your right eye causes you to stumble, pluck it out. It is better for you to enter the kingdom of God with one eye, than having two eyes, to be cast into the Gehenna of fire. Matthew 5:29; Mark 9:47.

Everyone recognizes that the eye should not be plucked out even if it does cause a person to stumble, and that no one enters the kingdom of God with only one eye. But 'the right eye' means falsity in a person's belief about the Lord; this is what must be plucked out. Then there are these things spoken by the Lord,

The lamp of the body is the eye. If therefore your eye is sound, your whole body will be full of light. If your eye is evil your whole body will be full of darkness. If therefore the light that is in you is darkness, how great is the darkness! Matthew 6:22-23; Luke 11:34.

Nor is 'the eye' used here to mean the eye, but an understanding composed of the truth of faith. This is why the eye is called 'the lamp of the body' and why the Lord says, 'If the light that is in you is darkness, how great is the darkness!' For 'darkness' in the spiritual sense is falsities constituting faith, 1839, 1860, 4418, 4531, 7688, 7711.

[3] There are these words too spoken by Him,

Why do you notice the speck which is in your brother's eye, but do not consider the plank that is in your own eye? Matthew 7:3-5.

'Noticing a speck in a brother's eye' means seeing something erroneous in a person's understanding of truth; 'the plank in one's own eye' is huge evil of falsity, since 'wood' in the internal sense means good and in the contrary sense evil, 643, 2784, 2812, 3720, 8354. Good is also represented in the next life by a plank, which is why those who pretend to have good within themselves are seen carrying a plank, walking in safety as they do so. If 'eye' and 'plank' did not have these meanings, would 'seeing a plank in an eye' have any meaning at all? If it is not known that 'eye' in the Word means the understanding of truth, which is faith, neither can it be known what is implied by the Lord's action when He healed the blind man,

He spat on the ground and made clay with His saliva, and said to him, Go, wash in the pool of Siloam. John 9:6-7.

Since all the Lord's miracles, like all Divine miracles, had to do with those things that belong to the Lord's kingdom and the Church, 7337, 8364, so did this miracle too.

4424. What the Lord's words quoted above embody in the internal sense becomes clear without explanation, for at this point the Lord uses comparisons rather than representatives and meaningful signs. Only the meaning of the words of the final verse has to be stated - 'He will cut him off and assign him his part with the hypocrites, where there is wailing and gnashing of teeth'.

He will cut him off means separation and removal from goods and truths, for people who have a knowledge of what is good and true, as those within the Church do, but who lead a life of evil are said to be cut off when that knowledge is removed from them; for in the next life their knowledge of good and truth is separated from them and they are restricted to evils and derivative falsities also. The reason why this takes place is so that they do not communicate with heaven through their knowledge of good and truth and with hell through their evil and consequent falsity, and thereby are left hanging between the two. A further reason is so that they do not profane goods and truths, as happens when these are mixed together with falsities and evils. The same is also meant by the Lord's words addressed to the one who hid his talent in the earth,

Take the talent from him and give it to him who has ten talents, for to everyone who has, it will be given, so that he may have in abundance; but from him who has not, even what he has will be taken away. Matthew 25:28-29.

And what the Lord says elsewhere has the same meaning - Matthew 13:12; also Mark 4:25, and Luke 8:18.

[2] And assign him his part with the hypocrites means that his lot, meant by 'part', lies with those who outwardly give the appearance of knowing the truth so far as doctrine is concerned, and of cherishing good so far as life is concerned, but who inwardly have no belief at all in truth nor any desire at all for good, who are 'the hypocrites'. People like this have become 'cut off' in the sense described here. Consequently when external things are taken away from these people, as happens to all in the next life, they are seen to be what they are like internally - people devoid of faith and charity. Yet they have pretended to have these, so that, capturing the attention of others, they could earn themselves positions of importance, monetary gain, and reputation. Within the Church that has become ruined virtually everyone is like this, for they have things that are external but none that are internal. Hence the interior aspects of those people are engulfed in the deluge described immediately above in 4423.

[3] Where there will be wailing and gnashing of teeth means their state in the next life, 'wailing' that state as regards evils, and 'gnashing of teeth' that state as regards falsities, for 'teeth' in the Word means lowest natural things - in the genuine sense truths going with these, and in the contrary sense falsities going with them. Teeth also correspond to those things. For these reasons 'the gnashing of teeth' means the clash of falsities and truths. People immersed in wholly natural things and governed by ideas resulting from sensory illusions, believing nothing which they do not see by means of these, are said to be where there is 'the gnashing of teeth', and in the next life seem to themselves to be there when they draw conclusions about the truths of faith on the basis of their own illusions. A Church in which good and truth have been brought to ruin teems with people such as these. The same is meant again in other places by the gnashing of teeth, as in Matthew,

The sons of the kingdom will be thrown into outer darkness, where there will be wailing and gnashing of teeth. Matthew 8:12.

'The sons of the kingdom' means those within the ruined Church.

'Darkness' means falsities, 4418, for they are in darkness when surrounded by the dark cloud mentioned above. 'The gnashing of teeth' means the clash of falsities with truths there. The same matter occurs in other places, such as Matthew 13:42, 50; 22:13; 25:30; and Luke 13:28.
