2 Samuel 21:8-13

But the king took the two sons of Rizpah the daughter of Ai´ah, whom she bare unto Saul, Armo´ni and Mephib´osheth; and the five sons of Michal the daughter of Saul, whom she brought up for A´dri-el the son of Barzil´lai the Meho´lathite: and he delivered them into the hands of the Gib´e-onites, and they hanged them in the hill before the LORD: and they fell all seven together, and were put to death in the days of harvest, in the first days, in the beginning of barley harvest. And Rizpah the daughter of Ai´ah took sackcloth, and spread it for her upon the rock, from the beginning of harvest until water dropped upon them out of heaven, and 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 Ai´ah, 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 Ja´besh–gil´e-ad, which had stolen them from the street of Beth–shan, where the Philistines had hanged them, when the Philistines had slain Saul in Gilbo´a: 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.
