Joshua 8:16-18

And all the people that were in Ai were called together to pursue after them: and they pursued after Joshua, and were drawn away from the city.

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

And the LORD said unto Joshua, Stretch out the spear that is in thy hand toward Ai; for I will give it into thine hand. And Joshua stretched out the spear that he had in his hand toward the city.
