Charles Ellicott Commentary Hebrews 7:24

"but he, because he abideth for ever, hath his priesthood unchangeable." — Hebrews 7:24 (ASV)

But this man.—Better, But He, because He remains for ever, has His priesthood inviolable (or, unchangeable). The former ordinance related to a race, and the individuals were continually passing away; since His life is “indissoluble” (Hebrews 7:16), none can trespass on His right and invade His priesthood. The rendering of the margin, “that passes not from one to another,” expresses nearly the same thought; but it is very doubtful whether the Greek will bear this meaning.
