Exodus 21:23-27

But if there is any further injury, then you shall appoint as a penalty life for life,

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

burn for burn, wound for wound, bruise for bruise.

“And if someone strikes the eye of his male or female slave and destroys it, he shall let the slave go free on account of the eye.

And if he knocks out a tooth of his male or female slave, he shall let the slave go free on account of the tooth.
