II Samuel 21:6, 9

let seven men of his descendants be delivered to us, and we will hang them before the LORD in Gibeah of Saul, whom the LORD chose.” And the king said, “I will give them.”

and he delivered them into the hands of the Gibeonites, and they hanged them on the hill before the LORD. So 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.
