Hebrews 7:27
He does not need, like those high priests, to offer up daily sacrifices, first for his own sins and then for the sins of the people, because he did this once for all when he offered up himself.
Hebrews 9:26
For then he would have had to suffer repeatedly since the foundation of the world. But now, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself.
Hebrews 10:1-10
For since the law has only a shadow of the good things to come and not the true form of these realities, it can never, by the same sacrifices which are continually offered year after year, make perfect those who draw near.
