Deuteronomy 21:6-9

YLT(i) 6 and all the elders of that city, who are near unto the slain one, do wash their hands over the heifer which is beheaded in the valley, 7 and they have answered and said, Our hands have not shed this blood, and our eyes have not seen— 8 receive atonement for Thy people Israel, whom Thou hast ransomed, O Jehovah, and suffer not innocent blood in the midst of Thy people Israel; and the blood hath been pardoned to them, 9 and thou dost put away the innocent blood out of thy midst, for thou dost that which is right in the eyes of Jehovah.
