In this verse, the writer of Hebrews points out a significant aspect of Jesus' priesthood. Traditionally, priests in Israel came from the tribe of Levi, specifically the line of Aaron. However, Jesus, who is recognized as the ultimate high priest, hailed from the tribe of Judah. This is noteworthy because no one from Judah had ever served as a priest under the old covenant. This unique aspect of Jesus' priesthood underscores its divine origin and legitimacy, not based on human tradition but on God's sovereign choice.
The mention of Jesus belonging to a different tribe serves to highlight the newness and superiority of His priesthood. It signifies a departure from the old covenant and the establishment of a new covenant, where Jesus serves as the eternal mediator between God and humanity. This new covenant offers believers direct access to God, forgiveness of sins, and a personal relationship with the Creator. Jesus' priesthood is characterized by grace, mercy, and eternal redemption, offering hope and assurance to all who believe.
