Hebrews 10:14 - Ellicott's Commentary On The Whole Bible

No repetition of His offering is needed, for by one offering He hath brought all unto “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 nigh 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.
