14 Now it happened, when the king of Ai saw it, that the men of the city hurried and rose early and went out against Israel to battle, he and all his people, at an appointed place before the plain. 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.
