2 Samuel 21:8-13

So the king took the two sons of Rizpah the daughter of Aiah, Armoni and Mephibosheth whom she had borne to Saul, and the five sons of Merab the daughter of Saul, whom she had borne to Adriel the son of Barzillai the Meholathite. Then he gave them into the hands of the Gibeonites, and they hanged them in the mountain before the LORD, so that the seven of them fell together; and they were put to death in the first days of harvest at the beginning of barley harvest. And Rizpah the daughter of Aiah took sackcloth and spread it for herself on the rock, from the beginning of harvest until it rained on them from the sky; and she allowed neither the birds of the sky to rest on them by day nor the beasts of the field by night. When it was told David what Rizpah the daughter of Aiah, the concubine of Saul, had done, then David went and took the bones of Saul and the bones of Jonathan his son from the men of Jabesh-gilead, who had stolen them from the open square of Beth-shan, where the Philistines had hanged them on the day the Philistines struck down Saul in Gilboa. He brought up the bones of Saul and the bones of Jonathan his son from there, and they gathered the bones of those who had been hanged.
