2 Samuel 21:5 KJV

3Wherefore David said unto the Gibeonites, What shall I do for you? and wherewith shall I make the atonement, that ye may bless the inheritance of the LORD?

4And the Gibeonites said unto 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.

5And they answered the king, The man that consumed us, and that devised against us that we should be destroyed from remaining in any of the coasts of Israel,

6Let seven men of his sons be delivered unto us, and we will hang them up unto the LORD in Gibeah of Saul, whom the LORD did choose. 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 them, between David and Jonathan the son of Saul.
