Levi is one of the twelve tribes of Israel. Because the Levites didn't participate in the sin of the golden calf, they were given the priesthood. Aaron and his sons served in the office of the high priest. The duties of the Levites included being teachers of the Torah, officers and judges, worship leaders and porters. They served in the tabernacle and temple and carried the ark of the covenant. In the promise land, they were given cities to live but were not given a land inheritance. The Melchizedek priesthood is better and superior to the Levitical priesthood and is the priesthood of the new covenant. However, the Levites will still perform their duties in the Messianic Kingdom in Ezekiel's temple. This is a very detailed study of the Levitical priesthood. As a result, your understanding of the Bible will be greatly enriched.
