Therefore the five kings of the Amorites, the king of Jerusalem, the king of Hebron, the king of Jarmuth, the king of Lachish, the king of Eglon, gathered themselves together, and went up, they and all their hosts, and encamped against Gibeon, and made war against it.
So Joshua returned, and all Israel with him, to the camp of Gilgal. But the five kings hid themselves in a cave. And so they came and told Joshua these five kings were hiding in the caves. So Joshua said, Throw a bunch of stones over the cave, seal it up, and stand outside and guard the thing ( Joshua 10:15-18 ).
