5The priests the sons of Levi shall come near, for them the LORD your God has chosen to minister to him, and to bless in the LORD’s name; and according to their word shall every controversy and every assault be decided.

6All the elders of that city which is nearest to the slain man shall wash their hands over the heifer whose neck was broken in the valley.

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

8Forgive, LORD, your people Israel, whom you have redeemed, and don’t allow innocent blood among your people Israel.” The blood shall be forgiven them.

9So you shall put away the innocent blood from among you, when you shall do that which is right in the LORD’s eyes.

10When you go out to battle against your enemies, and the LORD your God delivers them into your hands and you carry them away captive,
