Joshua 7:5-6

5who killed about thirty-six of them. They chased the Israelites from the city gate as far as the stone quarries and struck them down on the slopes. At this the hearts of the people melted in fear and became like water. 6Then Joshua tore his clothes and fell facedown to the ground before the ark of the LORD, remaining there till evening. The elders of Israel did the same, and sprinkled dust on their heads.
