What does the Bible say about the role of Jesus as High Priest?

In the Old Testament, the work of the priest was primarily to teach, pray, and offer sacrifices. Jesus is revealed as the appointed Great High Priest who embodied these roles perfectly. In John chapters 14-16, He instructs His disciples, imparting essential truths they would need after His departure. Not only does He teach, but He also intercedes for His people, as seen in His high priestly prayer in John 17. Finally, He completes the sacrificial aspect of His priestly work by offering Himself as the ultimate sacrifice, fulfilling the law and making atonement for the sins of His people. This sacrifice was necessary for the redemption of all who believe in Him, ending the need for the symbolic sacrifices of the Old Testament.
