1 Samuel 31:11-13

When the inhabitants of Jabesh-gilead heard what the Philistines had done to Saul, all the brave men stood and walked all night, and they took the bodies of Saul and his sons from the wall of Beth-shan, and they came to Jabesh and cremated them there. They took their bones and buried them under the tamarisk tree at Jabesh, and fasted [as a sign of mourning and respect] for seven days.
