11  If 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? 12  For, the priesthood being changed, there takes place of necessity a change of law also. 13  For 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. 14  For it is clear that our Lord has sprung out of Juda, as to which tribe Moses spake nothing as to priests. 15  And it is yet more abundantly evident, since a different priest arises according to the similitude of Melchisedec, 16  who has been constituted not according to law of fleshly commandment, but according to power of indissoluble life. 17  For it is borne witness, Thou art a priest for ever according to the order of Melchisedec. 18  For 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 God. 20  And by how much it was not without the swearing of an oath; 21  (for they are become priests without the swearing of an oath, but he with the swearing of an oath, by him who said, as to him, The Lord has sworn, and will not repent of it, Thou art priest for ever according to the order of Melchisedec;) 22  by so much Jesus became surety of a better covenant. 23  And they have been many priests, on account of being hindered from continuing by death; 24  but he, because of his continuing for ever, has the priesthood unchangeable.
