II Samuel 21:8-13

So the king took Armoni and Mephibosheth, the two sons of Rizpah the daughter of Aiah, whom she bore to Saul, and the five sons of Michal the daughter of Saul, whom she brought up for Adriel the son of Barzillai the Meholathite; and he delivered them into the hands of the Gibeonites, and they hanged them on the hill before the LORD. So 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. Now Rizpah the daughter of Aiah took sackcloth and spread it for herself on the rock, from the beginning of harvest until the late rains poured on them from heaven. And she did not allow the birds of the air to rest on them by day nor the beasts of the field by night. And David was told 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 street of Beth Shan, where the Philistines had hung them up, after the Philistines had struck down Saul in Gilboa. So 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.
