God gave his word; he won't take it back:
.........."You're the permanent priest."
......................This makes Jesus the guarantee of a far better way between us and God—one that really works! A new covenant.
......................Earlier there were a lot of priests, for they died and had to be replaced. But Jesus' priesthood is permanent. He's there from now to eternity to save everyone who comes to God through him, always on the job to speak up for them.
......................Hebrews 7:20-25
