Joshua

And he took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword.

And it was told Joshua, saying, The five kings are found hid in a cave at Makkedah.

And the king of Ai he hanged on a tree until eventide: and as soon as the sun was down, Joshua commanded that they should take his carcase down from the tree, and cast it at the entering of the gate of the city, and raise thereon a great heap of stones, that remaineth unto this day.
