20 When the men of Ai looked behind them, smoke from the town was filling the sky, and they had nowhere to go. For the Israelites who had fled in the direction of the wilderness now turned on their pursuers.

Matthew Henry's Commentary on Joshua 8:20

Commentary on Joshua 8:3-22

(Read Joshua 8:3-22)

Observe Joshua's conduct and prudence. Those that would maintain their spiritual conflicts must not love their ease. Probably he went into the valley alone, to pray to God for a blessing, and he did not seek in vain. He never drew back till the work was done. Those that have stretched out their hands against their spiritual enemies, must never draw them back.
