Joshua 7:12-13

12That is why the Israelites are running away from their enemies. They themselves must now be destroyed because they belong to me. If you want me to continue to help you, you must destroy everything that belongs to me. You should not have taken those valuable things for yourselves.

13So stand up now! Tell the people to make themselves clean. Make yourselves ready! Tomorrow you will come to stand in front of me. I, the Lord God of Israel tell you, “Israelite people, you have kept some of the things that I told you to destroy. You will not win against your enemies until you have removed those things!”
