13 So they set the people, even all the host that was on the north of the city, and their liers-in-wait that were on the west of the city; and Joshua went that night into the midst of the valley.

Matthew Henry's Commentary on Joshua 8:13

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.
