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.

895. 'The waters dried up from over the earth' means that falsities were not at that time apparent. This is clear from what has been stated. In particular these words mean that falsities had been separated from things of the will belonging to the member of this Church. The statement 'the waters dried up from over the earth' occurs at this point because here 'earth' means the person's will, which is nothing but evil desire. As stated already, the ground is situated in the understanding part of man's mind, in which part truths are sown. No sowing ever takes place in the will part, which in the spiritual man has been separated from the understanding part. This is why in the last part of this verse it is said that 'the face ¹ of the ground was dry'. With the member of the Most Ancient Church there was ground in the will part of his mind, where the Lord implanted goods. It was from goods therefore that he was able to know and perceive truth, that is, it was from love that he was able to possess faith. If the same thing were to happen today however, a person would inevitably and eternally perish, for his will is utterly corrupted. What implantation in the will part entails and what in the understanding part becomes clear from the consideration that the member of the Most Ancient Church had in fact enjoyed revelations through which from early childhood onwards he was led into a perception of goods and truths. But since they used to be implanted in the will part of his mind he perceived without any further instruction the countless aspects of any one general matter. He knew from the Lord the details and the finer points which nowadays men must learn before knowing about them. And even then they can know scarcely one thousandth of them. For the member of the spiritual Church knows nothing unless he acquires it by learning; and what he gets to know in this fashion he retains and believes to be true. Indeed if he learns something false and this is impressed on him as though it were true, he believes that as well, for he has no other perception than that a thing is true because he has in that way been persuaded of it. People who possess conscience derive from conscience a certain dictate. Yet with them a thing is true only because they have heard and learned that it is. This is what constitutes their conscience, as becomes clear from people who have a conscience of what is false.
