The Torah draws a substantive connection between the commandment concerning the priestly service on Yom Kippur and the death of Aharon's sons. By examining this connection in light of the sin of Aharon's sons and the sin of the Golden Calf, we can reach a deeper understanding of the significance of Yom Kippur and its service, and of standing before God.
