Deuteronomy 21
6 Ref 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 Ref Will say, This death is not the work of our hands and our eyes have not seen it.
8 Ref Have mercy, O Lord, on your people Israel whom you have made free, and take away from your people the crime of a death without cause. Then they will no longer be responsible for the man's death.
9 Ref So you will take away the crime of a death without cause from among you, when you do what is right in the eyes of the Lord.
