27 Unlike those other high priests, he does not need to offer sacrifices every day. They did this for their own sins first and then for the sins of the people. But Jesus did this once for all when he offered himself as the sacrifice for the people's sins.
Matthew Henry's Commentary on Hebrews 7:27
Commentary on Hebrews 7:26-28
(Read Hebrews 7:26-28)
Observe the description of the personal holiness of Christ. He is free from all habits or principles of sin, not having the least disposition to it in his nature. No sin dwells in him, not the least sinful inclination, though such dwells in the best of Christians. He is harmless, free from all actual transgression; he did no violence, nor was there any deceit in his mouth. He is undefiled. It is hard to keep ourselves pure, so as not to partake the guilt of other men's sins. But none need be dismayed who come to God in the name of his beloved Son. Let them be assured that he will deliver them in the time of trial and suffering, in the time of prosperity, in the hour of death, and in the day of judgment.
