Hebrews 7:15-22

15And this is even clearer if another priest arises in the likeness of Melchizedek,

16who has become a priest not by a legal regulation about physical descent but by the power of an indestructible life.

17For here is the testimony about him: “You are a priest forever in the order of Melchizedek.”

18On the one hand a former command is set aside because it is weak and useless,

19for the law made nothing perfect. On the other hand a better hope is introduced, through which we draw near to God.

20And since this was not done without a sworn affirmation – for the others have become priests without a sworn affirmation,

21but Jesus did so with a sworn affirmation by the one who said to him, “The Lord has sworn and will not change his mind, ‘You are a priest forever’” –

22accordingly Jesus has become the guarantee of a better covenant.
