[11] If therefore perfection by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron? [12] For the priesthood being changed, there is made of necessity a change also of the law. [13] For he of whom are spoken pertaineth to another tribe, of which no man gave attendance at the altar. [14] For it is evident that Lord sprang out of of which tribe Moses spake nothing concerning [15] And yet evident: for that after the similitude of Melchisedec there ariseth another priest, [16] Who is made, not after the law commandment, but after the power of an endless life. [17] For he testifieth, Thou art a priest for ever after the order of Melchisedec. [18] For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. [19] For the law nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God.
