The Majesty On High
Heb 7:16-17: Who is made, not after the law of a carnal
commandment, but after the power of an endless life. For
he testifieth, Thou art a priest for ever after the order of
Melchisedec.

Heb 7:21-22: (For those priests were made without an
oath; but this with an oath by him that said unto him, The
Lord sware and will not repent, Thou art a priest for ever
after the order of Melchisedec:) By so much was Jesus
made a surety of a better testament.
