Joshua 7:11-13
7:11 Israel has sinned; they have violated my covenantal commandment! They have taken some of the riches; they have stolen them and deceitfully put them among their own possessions.
7:12 The Israelites are unable to stand before their enemies; they retreat because they have become subject to annihilation. I will no longer be with you, unless you destroy what has contaminated you.
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.”
