Deuteronomy 21:4-6

Darby Translation

⁴ and the elders of that city shall bring down the heifer unto an ever-flowing watercourse, which is not tilled, nor is it sown, and shall break the heifer's neck there in the watercourse;

⁵ and the priests the sons of Levi shall come near; for them Jehovah thy God hath chosen to do service unto him, and to bless in the name of Jehovah; and according to their word shall be every controversy and every stroke.

⁶ And all the elders of that city, that are nearest unto him that is slain, shall wash their hands over the heifer whose neck is broken in the watercourse,
