John Gill Commentary Joshua 8:22

"And the others came forth out of the city against them; so they were in the midst of Israel, some on this side, and some on that side: and they smote them, so that they let none of them remain or escape." — Joshua 8:22 (ASV)

And the other issued out of the city against them That is, the ambush, or at least a part of them:

so that they were in the midst of Israel, some on this side, and some on that side ; or, as we commonly say, they were between two fires, the ambush on one side, the army of Israel on the other:

and they smote them, so that they let none of them remain or escape ; not one was saved alive, excepting their king, as in (Joshua 8:23) ; no quarter was given them, nor any suffered to make their escape.
