Joshua 8:22

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.
