2 Samuel 21:7-9

New Century Version

⁷ But the king protected Mephibosheth, the son of Jonathan, the son of Saul, because of the promise he had made to Jonathan in the Lord’s name. ⁸ The king did take Armoni and Mephibosheth,^[a] sons of Rizpah and Saul. (Rizpah was the daughter of Aiah.) And the king took the five sons of Saul’s daughter Merab. (Adriel son of Barzillai the Meholathite was the father of Merab’s five sons.) ⁹ David gave these seven sons to the Gibeonites. Then the Gibeonites killed them and hung them on stakes on a hill in the presence of the Lord. All seven sons died together. They were put to death during the first days of the harvest season at the beginning of barley harvest.
