2 Samuel 21:8-9

Darby(i) 8 And the king took the two sons of Rizpah the daughter of Aiah, whom she had borne to Saul, Armoni and Mephibosheth; and the five sons of [the sister of] Michal the daughter of Saul, whom she had borne to Adriel the son of Barzillai the Meholathite; 9 and he gave them into the hands of the Gibeonites, and they hanged them on the hill before Jehovah. And they fell all seven together, and were put to death in the first days of the harvest, in the beginning of barley harvest.
