2 Samuel 21:7-14

But the king spared Mephibosheth the son of Jonathan, the son of Saul, because of the LORD’S oath that was between David and Saul’s son Jonathan. So the king took the two sons of Rizpah the daughter of Aiah, whom she bore to Saul, Armoni and Mephibosheth, and the five sons of Merab the daughter of Saul, whom she had borne to Adriel the son of Barzillai the Meholathite. He handed them over to the Gibeonites, and they hanged them on the hill before the LORD, and the seven died together. They were put to death in the first days of the grain harvest, the beginning of the barley harvest [in the spring]. Rizpah the daughter of Aiah took sackcloth and spread it out for herself on the rock, from the beginning of harvest [in the spring] until [the autumn] rain fell on them; and she allowed neither the birds of the sky to rest on their bodies by day, nor the beasts of the field [to feed on them] by night. 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 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 when the Philistines had killed Saul in Gilboa. He brought up the bones of Saul and of Jonathan his son from there, and they gathered the bones of those who had been hanged [with their arms and legs broken]. They buried the bones of Saul and Jonathan his son in the country of Benjamin in Zela, in the tomb of Kish his father; and they did all that the king commanded. After that, God was moved by prayer for the land.
