3 So Joshua and the fighting-men got ready to go up against Ai; and Joshua took thirty thousand men of war, and sent them out by night.

Matthew Henry's Commentary on Joshua 8:3

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.
