Hebrews 9:7

9:7 But only the high priest enters once a year into the inner tent, and not without blood that he offers for himself and for the sins of the people committed in ignorance.

Hebrews 9:25-26

9:25 And he did not enter to offer himself again and again, the way the high priest enters the sanctuary year after year with blood that is not his own, 9:26 for then he would have had to suffer again and again since the foundation of the world. But now he has appeared once for all at the consummation of the ages to put away sin by his sacrifice.
