Musar zu Jirmejahu 2:23

The twelfth principle is that one needs to examine, know and recognize the greatness of the punishment for each one of his iniquities - for which of them is there lashes, for which of them is there a liability for excision, for which of them is there a death penalty from the court - in order that he know the greatness of his iniquity when he confesses it, and cry bitterly about that which bitterly angered [God. This is also] in order that he will enhance his submission and in order that he will fear from his iniquities. For [with] weighty sins, repentance only suspends their atonement whereas afflictions absolve them. And so is it written, (Jeremiah 2:23), "Look at your deeds in the valley, consider what you have done!" And this principle will be explained in the third chapter.
