Exodus 21:27

And if he smite out his man-servant's tooth or his maid-servant's tooth, he shall let him go free for his tooth's sake. The loss, not only of some member of the body, but even of a single tooth, as a result of the master's treatment, entitled the slave to his freedom. So far as Christians are concerned, they know that they should not hurt nor harm their neighbor in his body. They will not insist upon any law of retaliation, as the granting of indemnities is a function of the government, but will keep in mind the Lord's admonition to kindness and placableness.
