Hebrews 7:3, 8, 23-25

This Melchizedek has no father or mother, and no record of any of his ancestors. He was never born and he never died, but his life is like a picture of the Son of God, a King-Priest forever!

Although the Jewish priests received tithes, they all died—they were mortal. But Melchizedek lives on!

As additional proof, we know there were many priests under the old system, for they eventually died and their office had to be filled by another. But Jesus permanently holds his priestly office, since he lives forever and will never have a successor! So he is able to save fully from now throughout eternity, everyone who comes to God through him, because he lives to pray continually for them.
