Joshua 8:17-19

American Standard Version

¹⁷ And there was not a man left in Ai or Beth-el, that went not out after Israel: and they left the city open, and pursued after Israel.

¹⁸ And Jehovah said unto Joshua, Stretch out the javelin that is in thy hand toward Ai; for I will give it into thy hand. And Joshua stretched out the javelin that was in his hand toward the city. ¹⁹ And the ambush arose quickly out of their place, and they ran as soon as he had stretched out his hand, and entered into the city, and took it; and they hasted and set the city on fire.
