And Joshua and all Israel pretended to be beaten before them and fled in the direction of the wilderness.
15. And Joshua and all Israel made as if they were beaten, etc This is another stratagem. By pretending flight they draw off the enemy to a distance, leaving them no retreat afterwards into the city, which was in flames before they suspected that any disaster was to be apprehended in their rear.
We have here an account of the taking of Ai by stratagem. The stratagem here used, we are sure, was lawful and good; God himself appointed it, and we have no reason to think but that the like is lawful and good in other wars.
Commenting on Joshua 8:3-22
And Joshua and all Israel made as if they were beaten before them,.... 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, Jos 18:12.
