Hebrews 7:27

καθʼ ἡμέραν. A difficulty is suggested by this word, because the High Priest did not offer sacrifices daily, but only once a year on the Day of Atonement. In any case the phrase would be a mere verbal inaccuracy, since the High Priest could be regarded as potentially ministering in the daily sacrifices which were offered by the inferior Priests; or the one yearly sacrifice may be regarded as summing up all the daily sacrifices needed to expiate the High Priest’s daily sins (so that “daily” would mean “continually”). It appears however that the High Priest might if he chose take actual part in the daily offerings (Exodus 29:38; Exodus 29:44; Leviticus 6:19-22; Jos. B. J. Hebrews 7:5-7). It is true that the daily sacrifices and Minchah or “meat offering” had no recorded connexion with any expiatory sacrifices; but an expiatory significance seems to have been attached to the daily offering of incense (Leviticus 16:12-13, LXX.; Yoma, f. 44. 1). Wieseler’s notion that there is any reference to the Jewish Temple built by Onias at Leontopolis is entirely baseless. Both Philo (De Spec. Legg. § 53) and the Talmud use the very same expression as the writer, who seems to have been perfectly well aware that, normally and strictly, the High Priest only offered sacrifices on one day in the year (Hebrews 9:25; Hebrews 10:1; Hebrews 10:3). The stress may be on the necessity. Those priests needed the expiation by sacrifice for daily sins; Christ did not.

ἐφάπαξ, “once for all” (Hebrews 9:12; Hebrews 9:26; Hebrews 9:28; Hebrews 10:10; Romans 6:10). Christ offered one sacrifice, once offered, but eternally sufficient.

ἑαυτόν. The High Priest was also the Victim, Hebrews 8:3; Hebrews 9:12; Hebrews 9:14; Hebrews 9:25; Hebrews 10:10; Hebrews 10:12; Hebrews 10:14; Ephesians 5:2 (Lünemann).
