1 Samuel 14:38-39

38So Saul said to all the leaders of the army, ‘Come here. Someone has done a bad thing today. We must find out who has done it.

39The Lord is the one who rescues Israel. As surely as the Lord lives, I promise that I will punish the man who has done this bad thing. Whoever it is must die, even if it is my own son Jonathan.’ But nobody in the army said anything.
