1 Chronicles 10:10 (KJV)

And it came to pass on the morrow, when the Philistines came to strip the slain, that they found Saul and his sons fallen in mount Gilboa.

And when they had stripped him, they took his head, and his armour, and sent into the land of the Philistines round about, to carry tidings unto their idols, and to the people.

And they put his armour in the house of their gods, and fastened his head in the temple of Dagon.

And when all Jabesh–gilead heard all that the Philistines had done to Saul,

They arose, all the valiant men, and took away the body of Saul, and the bodies of his sons, and brought them to Jabesh, and buried their bones under the oak in Jabesh, and fasted seven days.
