Hebrews 9:25-28

25Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others; 26For then must he often have suffered since the foundation of the world: but now once in the end of the age hath he appeared to put away sin by the sacrifice of himself. 27And as it is appointed unto men once to die, but after this the judgment: 28So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
