It happened at the time of the going down of the sun, that Joshua commanded, and they took them down off the trees, and cast them into the cave in which they had hidden themselves, and laid great stones on the mouth of the cave, to this very day.
Israel’s leaders placed large stones over the grave of the Canaanite kings (Joshua 10:27) for the benefit of future observers (cf. Joshua 7:25). This constituted still another memorial to God’s faithfulness and power.
