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.
13. Joshua went that night into the midst of the valley—The deep and steep-sided glen to the north of Tell-el-hajar, into which one looks down from the tell, fully agrees with this account [Van De Velde]. Joshua himself took up his position on the north side of "the ravine"—the deep chasm of the wady El-Murogede; "that night"—means, while it was dark, probably after midnight, or very early in the morning (Joh 20:1). The king of Ai, in the early dawn, rouses his slumbering subjects and makes a hasty sally with all his people who were capable of bearing arms, once more to surprise and annihilate them.
