'Tooth' in the Bible

eye for eye, tooth for tooth, hand for hand, foot for foot,

And if he knocks out the tooth of his male servant or female servant, he must let the servant go free because of [the loss of] the tooth.

fracture for fracture, eye for eye, tooth for tooth; just as he has injured a man, so shall the same be done to him.

You shall not show pity [to the guilty one]: it shall be life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.

Like a broken tooth or an unsteady footIs confidence in an unfaithful man in time of trouble.
