Hebrews 7:15-19

And what we say is yet more abundantly evident, if after the likeness of Melchizedek there ariseth another priest, who hath been made, not after the law of a carnal commandment, but after the power of an endless life: for it is witnessed of him, Thou art a priest for ever After the order of Melchizedek. For there is a disannulling of a foregoing commandment because of its weakness and unprofitableness (for the law made nothing perfect), and a bringing in thereupon of a better hope, through which we draw nigh unto God.
