Musar על במדבר 11:2

עד אשר יצא מאפכם והיה לכם לזרא . When we observe how severely those people who knew no bounds to their greed were punished we learn the lesson that we should restrain our appetites even when it pertains to matters that are permissible. We should learn from our patriarch Jacob who had asked only for "bread to eat and clothes to wear" (Genesis 28,20).
