Joshua 8:20

And when the men of Ai looked behind them, their attention being drawn in that direction by the behavior of the Israelites, who turned to watch for the signal of the smoke's rising, they saw, and, behold, the smoke of the city ascended up to heaven, and they had no power to nee this way or that way, they were paralyzed with sudden terror; and the people that fled to the wilderness turned back upon the pursuers. The whole situation of the men of Ai, who now saw before them the enemy, behind them the burning town, is admirably pictured in a few strokes.
