SEV Biblia, Chapter 8:15
Entonces Josué y todo Israel, como vencidos, huyeron delante de ellos por el camino del desierto.
John Gill's Bible Commentary
Ver. 15. And Joshua and all Israel made as if they were beaten before them , etc.] Or smitten, as some of them might be in the pursuit: and fled by the way of the wilderness ; not a barren desert, but, according to Kimchi and Ben Melech, a place for the pasture of cattle; though perhaps it is the same with the wilderness of Bethaven, ( Joshua 18:12). Epiphanius makes mention of the wilderness of Bethel and Ephraim as near Jericho.
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.
