Joshua 7:4-5

4So about 3,000 Israelite men went to attack Ai. But the men of Ai made them run away.

5They chased the Israelites away from the gate of the city and they killed about 36 Israelite soldiers. They chased them down the hill as far as Shebarim. They killed the Israelites as they ran down the hill. When the people of Israel heard this, they became very frightened.
