In Tzav (“Command”), God tells Moses about the sacrifices offered in the Mishkan (Tabernacle), including a meal offering brought by the high priest, guilt offerings, and offerings of thanks. Moses initiates Aaron and Aaron’s sons for priestly service in the Mishkan.
Tetzave
Parashat Tetzave reports God’s commands to bring olive oil for the lamp (מְנוֹרָה, Menorah), make sacred garments for the priests, conduct an ordination ceremony, and make an incense altar.
