2 Samuel 21:7-9

Young's Literal Translation

⁷ and the king hath pity on Mephibosheth son of Jonathan, son of Saul, because of the oath of Jehovah that [is] between them, between David and Jonathan son of Saul;

⁸ and the king taketh the two sons of Rizpah daughter of Aiah, whom she bore to Saul, Armoni and Mephibosheth, and the five sons of Michal daughter of Saul whom she bare to Adriel son of Barzillai the Meholathite,

⁹ and giveth them into the hand of the Gibeonites, and they hang them in the hill before Jehovah; and the seven fall together, and they have been put to death in the days of harvest, in the first [days], the commencement of barley-harvest.
