LEV 24:20

20 If someone breaks one of another person’s bones, that person is allowed to break one of the bones of the person who injured him. If someone gouges out an eye of another person, that person is allowed to gouge out the eye of the person who injured him. If someone knocks out the tooth of another person, that person is allowed to knock out one of his teeth. What is done to the offender must be the same as what he did to the other person.
