8:19 Set the city on fire - Not all of it, as appears from ver.28, and because then they had lost that prey which God had allowed them; but part of it, enough to raise a smoke, and give notice to their brethren of their success.
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.
