Exodus 21:23-27

New International Version

²³ But if there is serious injury, you are to take life for life,^{(A) 24} eye for eye, tooth for tooth,^(B) hand for hand, foot for foot, ²⁵ burn 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. ²⁷ And an owner who knocks out the tooth of a male or female slave must let the slave go free to compensate for the tooth.
