And thine eye shall not pity,.... The false witness when convicted; this is directed to the judges, who should not spare such an one through favour or affection, but pronounce a righteous sentence on him, and see it executed, in proportion to the crime, and that according to the law of retaliation:but life shall go for life; in such a case where the life of a person must have gone, if the falsehood of the testimony had not been discovered, the false witness must suffer death; in other cases, where a member would have been lost, or the price of it paid for, the same penalty was to be inflicted:eye for eye, tooth for tooth, hand for hand, foot for foot; that is, the price of an eye an eye, &c.
see Ex 21:23.
