1 Chronicles 10:8-13

8The next day, when the Philistines came to strip the slain, they found Saul and his sons fallen on Mount Gilboa.

9And they stripped him and took his head and his armor, and sent messengers throughout the land of the Philistines to carry the good news to their idols and to the people.

10And they put his armor in the temple of their gods and fastened his head in the temple of Dagon.

11But when all Jabesh-gilead heard all that the Philistines had done to Saul,

12all the valiant men arose and took away the body of Saul and the bodies of his sons, and brought them to Jabesh. And they buried their bones under the oak in Jabesh and fasted seven days.

13So Saul died for his breach of faith. He broke faith with the Lord in that he did not keep the command of the Lord, and also consulted a medium, seeking guidance.
