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.

7711. 'And there will be thick darkness over the land of Egypt' means total deprivation of truth and good. This is clear from the meaning of 'thick darkness' as total deprivation of truth and good. Various places in the Word mention 'darkness' (tenebrae) and also at the same time 'thick darkness' (caligo), and in those places 'darkness' has reference to falsity and 'thick darkness' to evil together with it. But the word that is used in this verse to express thick darkness denotes pitch-black darkness (tenebrae densissimae), which in the internal sense means the kinds of falsities that well up from evil. Such falsities arise with those who have belonged to the Church and led an evil life contrary to the commandments of religious belief which they knew. The evil from which those falsities well up is the opposite of the Church, the opposite of heaven, the opposite of the Lord, and so the direct opposite of goodness and truth. This state is now described by 'thick darkness'.

[2] The fact that 'darkness' and 'thick darkness' are mentioned together in the Word, and that 'darkness' means the deprivation of truth, while 'thick darkness' means the deprivation of both truth and good, may be recognized in the following places: In Isaiah,

Judgement is far from us, and righteousness does not overtake us. We wait for light, but, behold, darkness; and for brightness, but we walk in thick darkness. We grope for the wall like the blind, and as if without eyes we grope; we stumble at midday as if it were twilight; among the living we are like the dead. Isaiah 59:9-10.

'Judgement is far from us, and righteousness does not overtake us' stands for the fact that there is no truth, and no good either, 'judgement' being used to refer to truth and 'righteousness' to refer to good, see 2235, 3997. 'Waiting for light' stands for awaiting truth, and 'waiting for brightness' stands for awaiting the good of truth since the brightness of light is derived from good. The fact that the expression 'darkness' is used in those verses as the opposite of 'light' and 'judgement', and so of truth, and 'thick darkness' as the opposite of 'brightness' and 'righteousness', and so of good, is self-evident. So it is that 'darkness' is the deprivation of truth, and 'thick darkness' the deprivation of both truth and good. In Amos,

Is not the day of Jehovah darkness and not light, and thick darkness, [and] no brightness in it? Amos 5:20.

Here the meaning is similar. In Joel,

The day of Jehovah is coming, a day of darkness and thick darkness, a day of cloud and gloom. Joel 2:2.

[3] In Zephaniah,

The day of Jehovah a day of vastation and devastation, a day of darkness and thick darkness. Zephaniah 1:15.

'Darkness' stands for the deprivation of truth, and 'thick darkness' for the deprivation of both truth and good. If 'thick darkness' were no different in meaning from 'darkness' it would be a pointless repetition, which is far from being a feature of the holy Word. In the Word it is common for a pair of expressions to describe one particular thing, the first having reference to truth or falsity, the second to good or evil. A like example occurs in Isaiah,

He will look to the earth, and behold, anguish and darkness; [he will be one] benighted by anguish, and by a thick darkness of colliding. ¹ Isaiah 8:11.

[4] 'Darkness' also means ignorance of the truth, such as exists among gentiles, and 'thick darkness' ignorance about what is good, in Isaiah,

On that day the deaf will hear the words of a book, and out of thick darkness and out of darkness the eyes of the blind will see. Isaiah 29:18.

In the same prophet,

If you satisfy the afflicted soul, your light will rise in the darkness, and your thick darkness will be as midday. Isaiah 58:10.

'Darkness' is falsities, see 7688.
