Exodus 21:22-27

22“If people are fighting and hit a pregnant woman and she gives birth prematurely Or she has a miscarriage but there is no serious injury, the offender must be fined whatever the woman’s husband demands and the court allows. 23But if there is serious injury, you are to take life for life, 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.
