Joshua 7:13

7:13 Get up! Ritually consecrate the people and tell them this: ‘Ritually consecrate yourselves for tomorrow, because the Lord God of Israel says, “You are contaminated, O Israel! You will not be able to stand before your enemies until you remove what is contaminating you.”

Joshua 22:19

22:19 But if your own land is impure, cross over to the Lord’s own land, where the Lord himself lives, and settle down among us. But don’t rebel against the Lord or us by building for yourselves an altar aside from the altar of the Lord our God.
