Hebrews 7:19-7:22

19. For the law made nothing perfect,
but the bringing in of a better hope did; by the which we draw nigh unto God.

                20. And inasmuch as not without an oath he was made priest: 21. (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:)

22. By so much was Jesus made a surety of a better testament.
