If you've followed along with us in our study of the Book of Exodus, you saw Moses receive on the mountaintop, the command of God and the instructions from God specifically on how to build the Tabernacle and also the instructions on the priesthood itself that would serve inside of the Tabernacle along with the instruments that would populate the Tabernacle. But now in Leviticus, we learn specifically how the instruments, how the priests, and how the Tabernacle would be used in order for the people of Israel to approach God.
