Deuteronomy 21:7

⁵And the priests the Levites shall come, because the Lord God has chosen them to stand by him, and to bless in his name, and by their word shall every controversy and every stroke be decided.

⁶And all the elders of that city who draw nigh to the slain man shall wash their hands over the head of the heifer which was slain in the valley;

— Deuteronomy 21:7 —

⁸Be merciful to thy people Israel, whom thou hast redeemed, O Lord, that innocent blood may not be charged on thy people Israel: and the blood shall be atoned for to them.

⁹And thou shalt take away innocent blood from among you, if thou shouldest do that which is good and pleasing before the Lord thy God.
