Hebrews 9:15

9:15 And so he is the mediator of a new covenant, so that those who are called may receive the eternal inheritance he has promised, since he died to set them free from the violations committed under the first covenant.

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.
