1 Samuel 31:8-9

8And it came to pass the next day, that the Philistines came to strip the slain, and they found Saul and his three sons fallen on mount Gilboa.

9And they cut off his head, and stripped off his armour, and sent [them] into the land of the Philistines round about, to announce the glad tidings in the houses of their idols, and to the people.
