What does the Bible say about the everlasting priesthood?

The concept of the everlasting priesthood is rooted in scripture, particularly in Numbers 25 and Hebrews 7. In Numbers, Phinehas is given a covenant of peace and an everlasting priesthood as a type pointing to the true eternal priest, Jesus Christ. Unlike the Levitical priests, who served temporarily and died, Christ's priesthood is based on His eternal life and perfect sacrifice. Hebrews emphasizes that Jesus, after the order of Melchizedek, is an eternal priest whose sacrifice fully atones for sin, establishing a permanent covenant of peace with God’s people.
