Joshua passed from Libnah, and all Israel with him, to Lachish, and encamped against it, and fought 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 ).
