SEV Biblia, Chapter 8:8
Y cuando la hubiereis tomado, le prenderéis fuego. Haréis conforme a la palabra del SEÑOR. Mirad que os lo he mandado.
Clarke's Bible Commentary - Joshua 8:8
Verse 8. Ye shall set the city on fire] Probably this means no more than that they should kindle a fire in the city, the smoke of which should be an indication that they had taken it. For as the spoils of the city were to be divided among the people, had they at this time set fire to the city itself, all the property must have been consumed, for the five thousand men did not wait to save any thing, as they immediately issued out to attack the men of Ai in the rear.
John Gill's Bible Commentary
Ver. 8. And it shall be, when ye have taken the city , etc.] Entered it and become masters of it: [that] ye shall set the city on fire ; not the whole city, only some outlying houses of it, to make a smoke which might be seen both by Israel and the men of Ai, for different purposes; for the spoil of the city was first to be taken before it was utterly burnt with fire: according to the commandment of the Lord shall ye do ; plunder the city, destroy the inhabitants of it, and then burn it: see I have commanded you ; delivered the command of the Lord unto them, and therefore were left without excuse, and could not plead ignorance; besides, he was their general, and he expected his orders to be obeyed, as they ought to have been.
Matthew Henry Commentary
Verses 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 neve draw them back.
