Charles Ellicott Commentary Hebrews 10:14

"For by one offering he hath perfected for ever them that are sanctified." — Hebrews 10:14 (ASV)

No repetition of His offering is needed, for by one offering He has brought all to “perfection,” and that “for ever.” In Hebrews 7:11 we have read that “perfection” did not come through the Levitical priesthood or through the law (Hebrews 10:19); the object of man’s hopes and of all priestly service has at last been attained, since through the “great High Priest” we draw near to God (Hebrews 7:19). In this is involved salvation to the uttermost (Hebrews 7:25).

The last word of this verse has occurred before, in Hebrews 2:11. As was there explained, it literally means those who are being sanctified, all those who, from age to age, through faith (Hebrews 10:22) receive as their own that which has been procured for all men.
