Hebrews 7:11-19

11If indeed then perfection were by the Levitical priesthood, for the people had their law given to them in connexion with it, what need [was there] still that a different priest should arise according to the order of Melchisedec, and not be named after the order of Aaron?

12For, the priesthood being changed, there takes place of necessity a change of law also.

13For he, of whom these things are said, belongs to a different tribe, of which no one has [ever] been attached to the service of the altar.

14For it is clear that our Lord has sprung out of Juda, as to which tribe Moses spake nothing as to priests.

15And it is yet more abundantly evident, since a different priest arises according to the similitude of Melchisedec,

16who has been constituted not according to law of fleshly commandment, but according to power of indissoluble life.

17For it is borne witness, Thou art a priest for ever according to the order of Melchisedec.

18For there is a setting aside of the commandment going before for its weakness and unprofitableness,

19(for the law perfected nothing,) and the introduction of a better hope by which we draw nigh to 1God.
