2 Samuel 21:8-13

But he gave them Saul’s two sons Armoni and Mephibosheth, whose mother was Rizpah daughter of Aiah. He also gave them the five sons of Saul’s daughter Merab, the wife of Adriel son of Barzillai from Meholah. The men of Gibeon executed them on the mountain before the LORD. So all seven of them died together at the beginning of the barley harvest. Then Rizpah daughter of Aiah, the mother of two of the men, spread burlap on a rock and stayed there the entire harvest season. She prevented the scavenger birds from tearing at their bodies during the day and stopped wild animals from eating them at night. When David learned what Rizpah, Saul’s concubine, had done, he went to the people of Jabesh-gilead and retrieved the bones of Saul and his son Jonathan. (When the Philistines had killed Saul and Jonathan on Mount Gilboa, the people of Jabesh-gilead stole their bodies from the public square of Beth-shan, where the Philistines had hung them.) So David obtained the bones of Saul and Jonathan, as well as the bones of the men the Gibeonites had executed.
