2 Samuel 21:6-10

6let seven men [chosen] from his sons (descendants) be given to us and we will hang them before the Lord [that is, put them on display, impaled with broken legs and arms] in Gibeah of Saul, the chosen one of the Lord.” And the king said, “I will give them.”

7But 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.

8So 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.

9He 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].

10Rizpah 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.
