2 Samuel 21:7

4 And the Gibeonites said to him, We will have no silver nor gold of Saul, nor of his house; neither for us shalt thou kill any man in Israel. And he said, What ye shall say, [that] will I do for you.

5 And they answered the king, The man that consumed us, and that devised against us [that] we should be destroyed from remaining within the borders of Israel,

6 Let seven men of his sons be delivered to us, and we will hang them up to the LORD in Gibeah of Saul, [whom] the LORD chose. And the king said, I will give [them].

7 But the king spared Mephibosheth, the son of Jonathan, the son of Saul, because of the LORD'S oath that [was] between them, between David and Jonathan the son of Saul.

8 But 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 Michal the daughter of Saul, whom she brought up for Adriel the son of Barzillai the Meholathite:

9 And he delivered them into the hands of the Gibeonites, and they hanged them on 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.

10 And Rizpah the daughter of Aiah 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.
