Deuteronomy 19:21 In-Context

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.
