2 Samuel 21:2-9

2So the king called the Gibeonites and spoke to them (now the Gibeonites were not of the sons of Israel but of the remnant of the Amorites, and 1the sons of Israel 2made a covenant with them, but Saul had sought to 3kill them in his zeal for the sons of Israel and Judah). 3Thus David said to the Gibeonites, “What should I do for you? And how can I make atonement that you may bless 4the inheritance of the Lord?” 4Then the Gibeonites said to him, “5We have no concern of silver or gold with Saul or his house, nor is it for us to put any man to death in Israel.” And he said, “I will do for you whatever you say.” 5So they said to the king, “6The man who consumed us and who planned 7to exterminate us from remaining within any border of Israel, 6let seven men from his sons be given to us, and we will 8hang them 9before the Lord in Gibeah of Saul, 10the chosen of the Lord.” And the king said, “I will give them.”

7But the king spared 11Mephibosheth, the son of Jonathan the son of Saul, 12because of the oath of the Lord which was between them, between David and Saul’s son Jonathan. 8So the king took the two sons of 13Rizpah the daughter of Aiah, Armoni and Mephibosheth whom she had borne to Saul, and the five sons of 1415Merab the daughter of Saul, whom she had borne to Adriel the son of Barzillai the 16Meholathite. 9Then he gave them into the hands of the Gibeonites, and they 17hanged them in the mountain before the Lord, so that the seven of them fell together; and they were put to death in the first days of harvest at 18the beginning of barley harvest.
