Deuteronomy 21:5 BBE

³  And whichever town is nearest to the body, the responsible men of that town are to take from the herd a young cow which has never been used for work or put under the yoke;

⁴  And they are to take the cow into a valley where there is flowing water, and which is not ploughed or planted, and there the neck of the cow is to be broken:

⁵  Then the priests, the sons of Levi, are to come near; for they have been marked out by the Lord your God to be his servants and to give blessings in the name of the Lord; and by their decision every argument and every blow is to be judged:

⁶  And all the responsible men of that town which is nearest to the dead man, washing their hands over the cow whose neck was broken in the valley,

⁷  Will say, This death is not the work of our hands and our eyes have not seen it.
