Tzav

G-d instructs the Cohanim (priests), through Moshe, the laws concerning the sacrifices. They are commanded to remove the ashes each morning from those sacrifices that were left burning over night. They are also instructed to ensure that a fire is continually burning on the altar. They are told how to offer the flour offerings that are brought by the nation. They are also told what sacrifice a Cohen is to bring on the day he is appointed as Priest. That same flour offering is brought daily by the High Priest.
Explicit instructions are given for the procedures for sacrificing the sin offerings (Chataot), the guilt offerings (Ashamim) and the peace offerings (Shelamim)
The people of Israel are commanded not to eat the cheilev (certain pieces of fat) or blood from any animal. The Torah commands that certain pieces of the meat from the Shelamim are given to the Cohanim to eat.
The portion ends with the anointing of Aaron and his sons as Cohanim. Moshe acts as High Priest during their initiation ceremony. He must dress the Cohanim, anoint them, and offer sacrifices on their behalf. The Cohanim are instructed to stay in the Ohel Moed (Communion Tent) for seven days to complete their inauguration.
