Exodus 21:24-27

24an eye for an eye, a tooth for a tooth, a hand for a hand, a foot for a foot.

25You must give him a burn for a burn, a wound for a wound, a bruise for a bruise.

26If a master hits the eye of his male slave or his female slave, he might destroy it. Then he must let the slave go away as a free person to pay for the loss of their eye.

27If he knocks out the tooth of his slave, he must also let the slave go away to pay for the loss of the tooth.
