2 Samuel 21:6

3 So David said to the Gibeonites, What may I do for you? how am I to make up to you for your wrongs, so that you may give a blessing to the heritage of the Lord?

4 And the Gibeonites said to him, It is not a question of silver and gold between us and Saul or his family; and it is not in our power to put to death any man in Israel. And he said, Say, then, what am I to do for you?

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.
