DEU 19:21

21 You must not pity people who are punished like that. The rule should be that a person who has murdered someone else must be executed; one of a person’s eyes must be gouged out if he has gouged out someone else’s eye, one tooth of a person who has knocked out the tooth of another person must be knocked out; one hand of a person who has cut off the hand of another person must likewise be cut off; one foot of a person who has cut off the foot of another person must also be cut off.”
