Deuteronomy 21:4-6 ▼

4 And the elders of that city shall bring down the heifer to a barren valley which has never been ploughed nor sown, and shall slaughter the heifer there in the valley;

5 And the 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 name of the LORD; and by their word shall every lawsuit and every attack be tried;

6 And all the elders of that city which is nearest to the slain man shall wash their hands over the heifer which is slaughtered in the valley;
