2 Samuel 13:19

Tamar put ashes. There was no concealment of her wrong, but, thrust out of the inner chamber into which Amnon had enticed her ( 2 Samuel 13:10 ), she cast ashes upon her head from the very fire which she had just used in cooking, and, rending her garment, hastened away with her hand on her head, and with cries of lamentation. If David had foreseen this sad sight when giving way to his passion for Bathsheba, he would have felt that sin is indeed "folly," and that its pleasure is followed by shame and bitter anguish.
