And the high priest was permitted to enter into the Holiest Sanctuary of All only once a year and he could never enter without first offering sacrificial blood for both his own sins and for the sins of the people.

And he has entered once and forever into the Holiest Sanctuary of All, not with the blood of animal sacrifices, but the sacred blood of his own sacrifice. And he alone has made our salvation secure forever!

For the Messiah did not enter into the earthly tabernacle made by men, which was but an echo of the true sanctuary, but he entered into heaven itself to appear before the face of God in our place. Under the old system year after year the high priest entered the most holy sanctuary with blood that was not his own. But the Messiah did not need to repeatedly offer himself year after year
