For it is clear that our Lord descended from Judah,1 and in regard to that tribe Moses said nothing about priests.
And what we have said is even more clear if another priest like Melchizedek appears,
one who has become a priest not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life.
For it is declared: "You are a priest forever, in the order of Melchizedek."a218
The former regulation is set aside because it was weak and useless319
(for the law made nothing perfect),4 and a better hope5 is introduced, by which we draw near to God.620
And it was not without an oath! Others became priests without any oath,
but he became a priest with an oath when God said to him: "The Lord has sworn and will not change his mind:7 'You are a priest forever.' "b822
Because of this oath, Jesus has become the guarantee of a better covenant.923
Now there have been many of those priests, since death prevented them from continuing in office;
but because Jesus lives forever, he has a permanent priesthood.10
