Joshua 7:4-6

New Century Version

⁴ So about three thousand men went up to Ai, but the people of Ai beat them badly. ⁵ The people of Ai killed about thirty-six Israelites and then chased the rest from the city gate all the way down to the canyon, killing them as they went down the hill. When the Israelites saw this, they lost their courage.

⁶ Then Joshua tore his clothes in sorrow. He bowed facedown on the ground before the Ark of the Lord and stayed there until evening. The leaders of Israel did the same thing. They also threw dirt on their heads to show their sorrow.
