Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
Neither - Nor yet.
By - through: as the means of His approach.
Goats ... calves. Not a bullock, such as the Levitical high priest offered for himself, and a goat for the people, on the day of atonement (Leviticus 16:6; Leviticus 16:15), year by year (whence the plural, goats ... calves). Besides the goat offered for the people, the blood of which was sprinkled before the mercy-seat, the high priest led forth a second-namely, the scapegoat: over its head he confessed the peoples sins, and sent it as the sin-bearer into the wilderness, implying that the atonement by the goat sin offering consisted in the transfer of the people's sins on the goat, and their consequent removal out of sight. The translation of sins on the victim, usual in other expiatory sacrifices, being omitted in case of the slain goat, but employed in the case the goat sent away, proved the two goats were regarded as one offering (Dr. Magee). Christ's death is symbolical by the slain goat: His resurrection to life by the living goat. Modern Jews substitute a cock for the goat as an expiation; the sins of the offerers being transferred to the entrails, and exposed on the house-top for the birds to carry out of sight, as the scapegoat did; the Hebrew for man and cock being similar х geber (H1397)] (Buxtorf).
By - through: the key unlocking the heavenly Holy of holies to Him х dia (G1223) tou (G3588) idiou (G2398) haimatos (G129)] 'through THE blood of His own' (cf. Hebrews 9:23).
Once, х efapax (G2178)] - "once for all."
Having obtained - thereby х heuramenos (G2147)] 'found for Himself:' a thing of insuperable difficulty, except divine omnipotence, self-devoting zeal, and love (Hebrews 5:7).
Eternal. The entrance of our Redeemer, once for all, into the heavenly Holiest, secures eternal redemption to us; whereas the Jewish high priest's entrance was repeated year by year, and the effect temporary and partail (cf. Matthew 20:28; Ephesians 1:7; Colossians 1:14; 1 Timothy 2:5; Titus 2:14; 1 Peter 1:19).
His blood, offered by Himself, purifies not only outwardly, as the Levitical sacrifices on the day of atonement, but inwardly unto the service of the living God (Hebrews 9:13-14). His death inaugurates the new covenant, and the heavenly sanctuary (Hebrews 9:15-23). His entrance into the true Holy of belies consummates His once-for-all offered sacrifice of atonement (Hebrews 9:24-26); His re-appearance alone remains to complete our redemption (Hebrews 9:27-28).
