Joshua 8:20
And when the men of Ai looked behind them, they saw, and, behold, the smoke of the city ascended up to heaven, and they had no power to flee this way or that way: and the people that fled to the wilderness turned back upon the pursuers.
And when the men of Ai looked behind them,.... On some account or another, perhaps observing that the army of Israel made a full stop and was gazing at the city:
they saw, and, behold, the smoke of the city ascended up to heaven; from whence they concluded an enemy was there, and had set fire to it:
and they had no power to flee this way or that way; for if they turned back to their city there was an enemy, how powerful they knew not, possessed of it, and whom they might expect would meet them; and if they pushed forward, there was the whole army of Israel against them, which now turned and faced them, showing no fear of them:
and the people that fled to the wilderness turned back upon the pursuers; the people of Israel, that fled by the way of the wilderness, Joshua 8:15, turned about, and fell upon the men of Ai that pursued them.
