1 Samuel 31:8-10

The next day, when the Philistines came to rob the dead, they found Saul and his three sons dead on Mount Gilboa. They cut off Saul’s head and stripped off his armor. Then they spread the good news all through Philistine country in the shrines of their idols and among the people. They displayed his armor in the shrine of the Ashtoreth. They nailed his corpse to the wall at Beth Shan.
