11 If, then, perfection was attainable through the Levitical priesthood+ (for it was a feature of the Law that was given to the people), what further need would there be for another priest to arise who is said to be in the manner of Mel·chizʹe·dek+ and not in the manner of Aaron? 12 For since the priesthood is being changed, it becomes necessary to change the Law as well.+ 13 For the man about whom these things are said came from another tribe, from which no one has officiated at the altar.+ 14 For it is clear that our Lord has descended from Judah,+ yet Moses said nothing about priests coming from that tribe.
15 And this becomes even clearer when another priest+ arises who is like Mel·chizʹe·dek,+ 16 who has become such, not by the legal requirement that depends on fleshly descent, but by the power of an indestructible life.+ 17 For it is said in witness of him: “You are a priest forever in the manner of Mel·chizʹe·dek.”+
18 So, then, the former commandment is set aside because it is weak and ineffective.+ 19 For the Law made nothing perfect,+ but the introduction of a better hope+ did, through which we are drawing near to God.+ 20 Also, inasmuch as this was not done without an oath being sworn 21 (for, indeed, there are men who have become priests without a sworn oath, but this one has become so through an oath sworn respecting him by the One who said: “Jehovah* has sworn, and he will not change his mind,* ‘You are a priest forever’”),+ 22 Jesus has accordingly become the guarantee* of a better covenant.+ 23 Furthermore, many had to become priests in succession+ because death prevented them from continuing as such, 24 but because he continues alive forever,+ his priesthood has no successors. 25 So he is able also to save completely those who are approaching God through him, because he is always alive to plead for them.+
