Hebrews 7:4, 8, 13, 15, 18

Now let me show you proof of how great this Melchizedek is: – Even though Abraham was the most honored and favored patriarch of all God’s chosen ones, he gave a tithe of the spoils of battle to Melchizedek.

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

Yet the One these things all point to, was from a different tribe and no one from that tribe ever officiated at God’s altar

And all this is made even clearer if there was another King-Priest raised up with the rank of Melchizedek.

The old order of priesthood has been set aside as weak and powerless.
