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.”
The former regulation is set aside because it was weak and useless
(for the law made nothing perfect), and a better hope is introduced, by which we draw near to God.
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: ‘You are a priest forever.’ ”
Because of this oath, Jesus has become the guarantor of a better covenant.
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.
Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them.
Such a high priest truly meets our need—one who is holy, blameless, pure, set apart from sinners, exalted above the heavens.
