The portion begins with G-d continuing to teach Moses many of the laws relating to the Mishkan service. However, while last week’s portion described the korbanos (offerings) from the perspective of the giver, this week the Torah focuses more directly on the Kohanim, providing details about their service. After first describing the maintenance of the fire which burned on the altar, the Torah discusses the various kinds of korbanos which Aaron, his sons, and the succeeding generations of Kohanim would be offering. The offerings must be brought with the proper intention and eaten in a state of spiritual purity. Finally, Moses performs the lengthy consecration service of the Mishkan, and anoints Aaron and his sons for their service in the Mishkan, in front of the entire congregation of Israel.
