Exodus 21:24-27

24eye for eye, tooth for tooth, hand for hand, foot for foot,

25burn for burn, wound for wound, bruise for bruise. 26“An owner who hits a male or female slave in the eye and destroys it must let the slave go free to compensate for the eye.

27And an owner who knocks out the tooth of a male or female slave must let the slave go free to compensate for the tooth.
