9052. 'Tooth for tooth' means if anything [is injured] in the outer part of the understanding. This is clear from the meaning of 'tooth' as the outer part of the understanding, and therefore as natural truth since this composes the life of that part of the understanding. The reason why 'the teeth' have this meaning is that like a mill they grind and so prepare the food which will serve as nourishment for the body, at this point the food which will serve as nourishment for the soul. The food that nourishes the soul is intelligence and wisdom; this food is first received, ground, and prepared by cognitions or knowledge of truth and good in the natural - intelligence and wisdom being what spiritual and celestial food is called, see 56-58, 680, 1480, 4792, 5147, 5293, 5340, 5342, 5576, 5579, 5915, 8562, 9003. From this one may see why it is that 'the teeth' means the outer part of the understanding. What this outer area is becomes clear from what has been shown immediately above in 9051 regarding the inner area of the understanding.

[2] 'The teeth' means natural truth, which belongs to the outer part of the understanding, and in the contrary sense falsity destroying that truth, as is clear from the following places in the Word Natural truth is meant in Moses,

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

These words too mention both eyes and teeth together. They refer to Judah, by whom the Lord's Divine Celestial is meant, 6363. 'His eyes' means the Lord's Divine Intellect, 6379, and 'his teeth' the Lord's Divine Natural, 6380, thus also Divine Truth in His Natural.

[3] In Amos,

I gave you emptiness of teeth in all your cities, and lack of bread in all your places. Amos 4:6

'Emptiness of teeth' stands for scarcity of truth, and 'lack of bread' for scarcity of good.

All this makes plain what the gnashing of teeth is among those in hell, Matthew 8:12; 13:42, 50; 22:13; 25:30; Luke 13:28. It is the clash of falsities with the truths of faith, 4424 (end); for as has been stated, 'the teeth' in the contrary sense means falsity destroying truth, as in David,

Rise up, O Jehovah; save me, O my God! For You will strike all my enemies on the jaw, You will break the teeth of the wicked. Psalms 3:7.

'Breaking the teeth of the wicked' stands for breaking the falsities that the wicked use to destroy truths. In the same author,

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

'The teeth of lions' stands for falsities destructive of truths, 'lions' being falsities arising from evil in their power, 6367, 6369.

[4] In the same author,

O God, destroy their teeth in their mouth; tear out ¹ the molars of the young lions. Psalms 58:6.

A nation has come up over My land, strong and innumerable; its teeth are the teeth of a lion, and it has the molars of a fierce lion. It has turned My vine into a waste, and My fig tree into froth. Joel 1:6-7.

'Teeth' and 'molars' stand for falsities destructive of the Church's truths. 'Vine' is the spiritual Church, 1069, 5113, 6376, and 'fig tree' is its natural good, 217, 4231, 5113. The fact that 'teeth' has that meaning is also evident from their being attributed to a nation which will lay waste. In John,

The shapes of the locusts were like horses prepared for war. They had hair like women's hair, and their teeth were like lions'. Revelation 9:7-8.

'The locusts' are those who are steeped in external falsities, 7643, from which it is evident that again 'teeth' are falsities destructive of truths.

3735. 'And clothing to wear' means being joined to Divine Truth. This is clear from the meaning of 'clothing' as truth, dealt with in 1073, 2576, Divine Truth here since the Lord is the subject; and from the meaning of 'wearing' as making it one's own and being joined to it. As for the nature of the internal sense of the Word, that becomes clear from these and all other details; that is to say, when the sense of the letter refers to bread and to clothing, and also when it does so within historical narrative, as here in 'If God will give me bread to eat and clothing to wear', the angels present with a person at the time have no thought at all of bread but of the good of love, and in the highest sense, of the Lord's Divine Good. Nor do they have any thought at all of clothing but of truth, and in the highest sense, of the Lord's Divine Truth. To them such things as are referred to in the sense of the letter are simply objects for thought regarding heavenly and Divine matters, for such things are vessels existing in the ultimate degree of order.

[2] So when with holiness of mind a person thinks about bread - for example, when he thinks about the bread in the Holy Supper, or about the daily bread in the Lord's Prayer - that thought which he has about bread serves the angels present with him as an object for thought regarding the good of love which comes from the Lord. For the angels do not take hold of anything at all of the person's actual thought concerning bread, but instead their thought concerns good; for such is the correspondence between the two. It is similar when with holiness of mind a person thinks about clothing. The angels' thought in that case concerns truth. So it is with everything else in the Word. From this the nature of the joining together of heaven and earth by means of the Word becomes clear; that is to say, the joining together is such that when with holiness of mind anyone reads the Word he is joined by means of such correspondences more closely to heaven, and through heaven to the Lord, even though that person's thought is concerned solely with things in the Word which are stated in the sense of the letter. His holiness of mind at that time is the product of the influx of celestial and spiritual thoughts and affections such as exist with angels.

[3] So that such influx might exist and from that influx man might be joined to the Lord, the Lord has instituted the Holy Supper where it is explicitly stated that the Lord is the bread and wine. For the Lord's body means His Divine love, and the reciprocal love in man, love such as exists with celestial angels, while His blood in a similar way means His Divine love, and the reciprocal love in man, but love such as exists with spiritual angels. From this it is evident how much of the Divine there is within every individual part of the Word, though man does not know what that Divine content is or the nature of it. People however who, while in the world, have led a good life enter after death into cognitions and a perception of all those things, for at that time they cast off earthly and worldly things and take to themselves heavenly ones, and have, like angels, spiritual and celestial ideas.
