Musar for Sanhedrin 162:5

מי שלקה ושנה: שנה אע"ג דלא שילש לימא מתני' דלא כרשב"ג דאי רשב"ג הא אמר עד תלת זימני לא הויא חזקה

so that he is already liable to death [at the hand of God], but the time of his death has not yet come: since, however, he abandoned himself [to sin, by transgressing a third time], we hasten his death. R. Jacob said to R. Jeremiah b. Tahlifa: 'Come, I will interpret it to you. This treats of flagellation for one sin involving extinction [which was twice repeated]: but [if he committed]two or three different sins each involving extinction, It may merely be his desire to experience sin, and not a complete abandonment thereto.'<span class="x" onmousemove="('comment',' So that there is hope for his reformation; consequently we do not hasten his death.
