Deuteronomy 19:19-21

New Revised Standard Version, Anglicised

¹⁹ then you shall do to the false witness just as the false witness had meant to do to the other. So you shall purge the evil from your midst. ²⁰ The rest shall hear and be afraid, and a crime such as this shall never again be committed among you. ²¹ Show no pity: life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
