(Proverbs 5:23): "He shall die for lack of discipline" — he shall die in his iniquity, because he did not heed words of discipline. "And in the greatness of his folly he shall go astray" (Proverbs 5:23) — he did not wish to wander in words of Torah [to immerse himself and lose himself in study]; now, in the greatness of his folly, he shall go astray.
He Dies For Lack Of Discipline And Strays In His Folly
Midrash Mishlei 5:9
(משלי ה כג): "הוא ימות באין מוסר" - הוא ימות בעוונו, שלא שמע דברי מוסר. "וברב אולתו ישגה" - לא רצה לשגות בדברי תורה, עכשיו ברוב איוולתו ישגה.
