ייִדישער מחשבֿה אויף קהלת 9:2

Rabbi Ami said in Talmud Shabbat, 55: "There is no death without sin, and no suffering without guilt." When the angels questioned G'd why He had decreed death on Adam, G'd said that He had commanded Adam only one single commandment, and the latter had been unable to handle it. Upon the question why Moses and Aaron, each of whom had fulfilled many hundreds of commandments had been condemned to die, G'd replied that the righteous and the wicked share the same destiny. This is the meaning of the verse in Kohelet 9,2, "the righteous and the wicked share the same fate." In a Baraita Rabbi Shimon ben Eleazar elaborated, "Moses and Aaron died because of their sin."
