Joshua 10:18

And Joshua said, roll great stones upon the mouth of the cave ,.... To keep the kings in, that they might not make their escape, until he had convenient time to have them brought before him, and be treated by him as they deserved; and no doubt there were plenty of stones about the hill or mountain, in which this cave was, fit for this purpose:

and set men by it for to keep them ; as a guard upon them, to prevent their escape.
