King James Version
“And thine eye shall not pity; life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.”
Context
18And the judges shall make diligent inquisition: and, behold, the witness a false witness, hath testified falsely against his brother;
19Then shall ye do unto him, as he had thought to have done unto his brother: so shalt thou put the evil away from among you.
20And those which remain shall hear, and fear, and shall henceforth commit no more any such evil among you.
21And thine eye shall not pity; life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
