'Folly' in the Bible

Then the man, the master of the house, went out and said to them, “No, my fellow citizens, please do not act so wickedly. Since this man has come to my house [as my guest], do not commit this sacrilege.

So I took my concubine and cut her [corpse] in pieces and sent her [body parts] throughout the land of the inheritance of Israel; for the men of Gibeah have committed a lewd and disgraceful act in Israel.

and we will take ten men out of a hundred throughout the tribes of Israel, and a hundred out of a thousand, and a thousand out of ten thousand to bring provisions for the men, so that when they come to Gibeah of Benjamin, they may punish them for all the despicable acts which they have committed in Israel.”
