Hebrews 5 explains the nature of Christ ‘s Priesthood. He is not a Levite after the order of Aaron. Rather, His priesthood both predates and postdates the Law of Moses because His priesthood is eternal. Hebrews 5 describes Jesus as a priest after the order of Melchizedek, the priest/king to whom Abram paid tithe and from whom he received blessing. Jesus is a greater High Priest.
