13 So all the people were in their places, the army on the north side of the town and the secret force on the west; and that night Joshua went down into 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.
