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.

9936. 'And it shall be on Aaron's forehead' means from the Lord's Divine Love. This is clear from the representation of 'Aaron' as the Lord in respect of Divine Good, which is the Good of His Divine Love, dealt with in 9806; and from the meaning of 'forehead', when the Lord is the subject, as His Divine Love. 'The Lord's face', which is the same as 'Jehovah's face', means all attributes of Divine Love, such as mercy, peace, goodness, or wisdom, 222, 223, 5585, 6848, 6849, 9306, 9545, 9546. These are meant by 'Jehovah's face' or 'the Lord's face' because in general 'the face' means a person's interiors, that is, a person's affections and consequent thoughts, thus the things which constitute his love and faith, see the places referred to in 9546. These are meant by 'the face' because they shine from the face, as if seen in their imprint or image, which also is why the face is called the image of the mind. So it is that when 'face' is mentioned in connection with Jehovah or the Lord the attributes of His Divine Love are meant. 'Forehead' in particular means Divine Love itself, because interiors have been allotted their own provinces in the face. The interiors that belong to love reside in the province of the forehead, those belonging to wisdom and intelligence in the province of the eyes, those belonging to perception in the province of the nose, and those belonging to utterance in the province of the mouth.

[2] From all this it is evident why 'forehead' - when the Lord, represented by Aaron, is the subject - means Divine Love. Since someone's forehead corresponds to his love those governed by celestial love, that is, by love to the Lord derived from the Lord, are said 'to have a sign on their foreheads', meaning that they are under the Lord's protection because they abide in His Love, as in Ezekiel,

Jehovah said, Go through the middle of Jerusalem and make a sign on the foreheads of the men (vir) who groan and sigh over all the abominations done in the midst of it, and strike; do not let your eye spare. But against any man (vir) on whom there is a sign do not go near. Ezekiel 9:4-6.

In John, in the Book of Revelation,

Behold, a Lamb standing on Mount Zion, and with Him a hundred and forty-four thousand, having His Father's name written on their foreheads. Revelation 14:1.

In the same book,

They will see the face of God and of the Lamb, and His name will be on their foreheads. Revelation 22:4.

In the same book,

It was declared that they should not harm the grass of the earth, or any green thing, or any tree, but only the people who did not have God's sign on their foreheads. Revelation 9:4.

[3] 'Having God's sign on their foreheads' and 'having God and the Lamb's name on them' stand for their being kept safe from molestation by evils from hell, because they abide in the Lord through love. 'The grass' and 'any green thing', which were not to be harmed, stand for true factual knowledge by means of which the truth of faith develops, 7571, 7691; and 'any tree', which too was not to be harmed, stands for the perception of truth springing from good, 103, 2163, 2722, 2972, 4552, 7692.

[4] In Moses,

You shall love Jehovah your God with all your heart, and with all your soul, and with all your strength. You shall bind these words as a sign onto your hand, and let them be as frontlets between your eyes. Deuteronomy 6:4-5, 8.

'As frontlets' stands for as a sign of love to Jehovah God. The words 'between your eyes' are used because intelligence and wisdom which are born from that love are meant by 'eyes'; and wisdom born from that love consists in having God constantly before one's eyes. This is self-evidently so because the subject is love to Jehovah God. The declaration that they should love Him with all their heart, with all their soul, and with all their strength, means that they should do so with all their human powers. 'With the heart' means with the will where the good of love resides, 7542, 9050, 9300, 9495; and 'with the soul' means with the understanding where the truth of faith resides, and so with faith, 9050. These two powers belong to the internal man. 'With all their strength' means with those powers of will and understanding as they exist in the external man. The strength and power of the love of both, of the external man and of the internal, are meant by 'hands', 4931-4937, 7518; and this is why it says that those words were to be bound 'as a sign on the hand'.

[5] Since 'the forehead' by virtue of its correspondence means celestial or heavenly love with those who are good, with those who are bad it accordingly means hellish love, which is the opposite of heavenly. The forehead of the latter is called a bronze forehead in Isaiah 48:4, and an obstinate forehead in Ezekiel 3:7-8. And in reference to those ruled by hellish love it is said that they had the mark of the beast on their foreheads, Revelation 13:16; 14:9; 20:4, and also the name of Babylon on their foreheads, Revelation 17:5.
