Hebrews 7:26-28

For such a high priest became us, holy, guileless, undefiled, separated from sinners, and made higher than the heavens; who needeth not daily, like those high priests, to offer up sacrifices, first for his own sins, and then for the sins of the people: for this he did once for all, when he offered up himself. For the law appointeth men high priests, having infirmity; but the word of the oath, which was after the law, appointeth a Son, perfected for evermore.
