14 And as soon as the king of Ai saw this, he and all his people, the men of the city, hurried and went out early to the appointed place toward the Arabah to meet Israel in battle. But he did not know that there was an ambush against him behind the city.
Matthew Henry's Commentary on Joshua 8:14
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.
