Joshua 8:18-19

18Then the Lord said to Joshua, “1Reach out with the sword that is in your hand toward Ai, for I will hand it over to you.” So Joshua reached out with the sword that was in his hand toward the city.

19Then the men in ambush rose quickly from their place, and when he had reached out with his hand, they ran and entered the city and captured it, and they quickly set the city on fire.
