Hebrews 7
17 Ref For he testifieth, Thou art a priest for ever after the order of Melchisedec.
18 Ref For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof.
19 Ref 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 Ref (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 Ref By so much was Jesus made a surety of a better testament.
23 Ref And they truly were many priests, because they were not suffered to continue by reason of death:
24 Ref But this man, because he continueth ever, hath an unchangeable priesthood.
