Hebrews 7:15-19

And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest, 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. For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God.
