2 Samuel 21:8-13

But the king took the two sons of Rizpah the daughter of Aiah, whom she bare unto Saul, Armoni and Mephibosheth; and the five sons of Michal the daughter of Saul, whom she bare to Adriel the son of Barzillai the Meholathite: And he delivered them into the hands of the Gibeonites, and they hanged them in the mountain before the LORD, and they fell all seven together: and they were put to death in the days of harvest, in the first days, at the beginning of barley harvest. And Rizpah the daughter of Aiah took sackcloth, and spread it for her upon the rock, from the beginning of harvest until water was poured upon them from heaven; and she suffered neither the birds of the air to rest on them by day, nor the beasts of the field by night. And it was told David what Rizpah the daughter of Aiah, the concubine of Saul, had done. And David went and took the bones of Saul and the bones of Jonathan his son from the men of Jabesh-gilead, which had stolen them from the street of Beth-shan, where the Philistines had hanged them, in the day that the Philistines slew Saul in Gilboa: and he brought up from thence the bones of Saul and the bones of Jonathan his son; and they gathered the bones of them that were hanged.
