2 Samuel 21:6, 9

let seven men of his sons be delivered unto us, and we will hang them up unto the LORD in Gibeah of Saul, whom the LORD did choose. And the king said, I will give them.

and he delivered them into the hands of the Gibeonites, and they hanged them in the hill before the LORD: and they fell all seven together, and were put to death in the days of harvest, in the first days, in the beginning of barley harvest.
