Joshua 7:10-13

So the LORD said to Joshua, “Get up! Why is it that you have fallen on your face? Israel has sinned; they have also transgressed My covenant which I commanded them [to keep]. They have even taken some of the things under the ban, and they have both stolen and denied [the theft]. Moreover, they have also put the stolen objects among their own things. That is why the soldiers of Israel could not stand [and defend themselves] before their enemies; they turned their backs [and ran] before them, because they have become accursed. I will not be with you anymore unless you destroy the things under the ban from among you. Rise up! Consecrate the people and say, ‘Consecrate yourselves for tomorrow, for thus says the LORD, the God of Israel: “There are things under the ban among you, O Israel. You cannot stand [victorious] before your enemies until you remove the things under the ban from among you.”
