Heb 7:11-19

11^* If, then, perfection came through the levitical priesthood, on the basis of which the people received the law, what need would there still have been for another priest to arise according to the order of Melchizedek, and not reckoned according to the order of Aaron?^e 12When there is a change of priesthood, there is necessarily a change of law as well. 13Now he of whom these things are said^* belonged to a different tribe, of which no member ever officiated at the altar. 14It is clear that our Lord arose from Judah,^* and in regard to that tribe Moses said nothing about priests.^f 15^* It is even more obvious if another priest is raised up after the likeness of Melchizedek, 16who has become so, not by a law expressed in a commandment concerning physical descent but by the power of a life that cannot be destroyed.^* 17For it is testified:

“You are a priest forever

according to the order of Melchizedek.”^g

18On the one hand, a former commandment is annulled because of its weakness and uselessness,^h 19for the law brought nothing to perfection; on the other hand, a better hope^* is introduced, through which we draw near to God.
