4:14&version=NIV1984
23 Now there have been many of those priests, since death prevented them from continuing in office; 24 but because Jesus lives forever, he has a permanent priesthood. 25 Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them.
26 Such a
high priest meets our need—one who is holy, blameless, pure, set apart
from sinners, exalted above the heavens. 27
Unlike the other high priests, he does not need to offer sacrifices day
after day, first for his own sins, and then for the sins of the people.
He sacrificed for their sins once for all when he offered himself. 28
For the law appoints as high priests men who are weak; but the oath,
which came after the law, appointed the Son, who has been made perfect
forever.
