See the source sheet here This shiur focuses on a pivotal moment in the inauguration of the Mishkan, focusing on two instances of blessing the people by Aaron and then by both Moses and Aaron, as described in Leviticus 9. Commentators debate the nature of Aaron's initial blessing, whether it was the established Priestly Blessing or a different one, and explore why Moses joined in the second blessing. They also discuss the appearance of God's glory following the second blessing, identifying it with the fire that consumed the offerings on the altar, and consider the reasons behind the fire's arrival and the subsequent reaction of the people. Some sources connect these events to Aaron's feelings of inadequacy and the need for Moses' support, and even link the actions of Aaron's sons, Nadav and Avihu, to this sequence of events.
