2nd Samuel 21:8

5 And they said to the king, As for the man by whom we were wasted, and who made designs against us to have us completely cut off from the land of Israel,

6 Let seven men of his family be given up to us and we will put an end to them by hanging them before the Lord in Gibeon, on the hill of the Lord. And the king said, I will give them.

7 But the king did not give up Mephibosheth, the son of Saul's son Jonathan, because of the Lord's oath made between David and Jonathan, the son of Saul.

8 But the king took Armoni and Mephibosheth, the two sons of Saul to whom Rizpah, the daughter of Aiah, had given birth; and the five sons of Saul's daughter Merab, whose father was Adriel, the son of Barzillai the Meholathite:

9 And he gave them up to the Gibeonites, and they put them to death, hanging them on the mountain before the Lord; all seven came to their end together in the first days of the grain-cutting, at the start of the cutting of the barley.

10 And Rizpah, the daughter of Aiah, took haircloth, placing it on the rock as a bed for herself, from the start of the grain-cutting till rain came down on them from heaven; and she did not let the birds of the air come near them by day, or the beasts of the field by night.

11 And news was given to David of what Rizpah, the daughter of Aiah, one of Saul's wives, had done.
