2 Samuel 21:7 WEB

⁵  They said to the king, The man who consumed us, and who devised against us, [that] we should be destroyed from remaining in any of the borders of Israel,

⁶  let seven men of his sons be delivered to us, and we will hang them up to Yahweh in Gibeah of Saul, the chosen of Yahweh. The king said, I will give them.

⁷  But the king spared Mephibosheth, the son of Jonathan the son of Saul, because of Yahweh'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 bore to Adriel the son of Barzillai the Meholathite:

⁹  He delivered them into the hands of the Gibeonites, and they hanged them in the mountain before Yahweh, and they fell [all] seven together. They were put to death in the days of harvest, in the first days, at the beginning of barley harvest.
