³³ So ye shall not pollute the land wherein ye are: for blood it defileth the land: and the land cannot be cleansed of the blood that is shed therein, but by the blood of him that shed it.

21 If one be found slain in the land which the Lord thy God giveth thee to possess it, lying in the field, and it be not known who hath slain him:

² Then thy elders and thy judges shall come forth, and they shall measure unto the cities which are round about him that is slain:

³ And it shall be, that the city which is next unto the slain man, even the elders of that city shall take an heifer, which hath not been wrought with, and which hath not drawn in the yoke;

⁴ And the elders of that city shall bring down the heifer unto a rough valley, which is neither eared nor sown, and shall strike off the heifer's neck there in the valley:

⁵ And the priests the sons of Levi shall come near; for them the Lord thy God hath chosen to minister unto him, and to bless in the name of the Lord; and by their word shall every controversy and every stroke be tried:

⁶ And all the elders of that city, that are next unto the slain man, shall wash their hands over the heifer that is beheaded in the valley:

⁷ And they shall answer and say, Our hands have not shed this blood, neither have our eyes seen it.

⁸ Be merciful, O Lord, unto thy people Israel, whom thou hast redeemed, and lay not innocent blood unto thy people of Israel's charge. And the blood shall be forgiven them.

⁹ So shalt thou put away the guilt of innocent blood from among you, when thou shalt do that which is right in the sight of the Lord.

²⁴ And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.

⁹ And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:

¹⁰ And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?
