9063. 'He shall send him away free for his tooth' means that it cannot serve the internal man any longer. This is clear from the meaning of 'sending away free' as releasing from service, thus not serving any longer, as above in 9061; and from the meaning of 'tooth' as the level of the senses, dealt with immediately above in 9062. The situation in these matters may be recognized from what has been shown just above in 9061 regarding the condition of the internal man when the external man has been injured. Its condition is similar when the sensory level has been injured, for this is the lowest level in the natural man. This level too must be regenerated if a person is to be regenerated completely, see 6844, 6845, 7645. It is clear to anyone that these regulations concerning the eye or the tooth of a male slave or a female slave contain arcana which nobody can see without the help of the internal sense. For without some hidden reason why would it be stipulated that slaves should be released and go free because of an eye or because of a tooth, but not because of other parts of the body if they were badly damaged? But that hidden reason is made evident when one knows what is meant in the spiritual sense by 'eye' and by 'tooth'. And when one knows that, the reason for the stipulation comes to light.
