Enemies Discovered Hiding In A Cave

Joshua 10:16-21
 
16  But these five kings fled, and hid themselves in a cave at Makkedah. 
17  And it was told Joshua, saying, The five kings are found hid in a cave at Makkedah. 
18  And Joshua said, Roll great stones upon the mouth of the cave, and set men by it for to keep them: 
19  And stay ye not, but pursue after your enemies, and smite the hindmost of them; suffer them not to enter into their cities: for the LORD your God hath delivered them into your hand. 
20  And it came to pass, when Joshua and the children of Israel had made an end of slaying them with a very great slaughter, till they were consumed, that the rest which remained of them entered into fenced cities. 
21  And all the people returned to the camp to Joshua at Makkedah in peace: none moved his tongue against any of the children of Israel.
