The former priests were many in number, because they were prevented by death from continuing in office; but he holds his priesthood permanently, because he continues for ever. Consequently he is able for all time to save those who draw near to God through him, since he always lives to make intercession for them. For it was fitting that we should have such a high priest, holy, blameless, unstained, separated from sinners, exalted above the heavens. He has no need, like those high priests, to offer sacrifices daily, first for his own sins and then for those of the people; he did this once for all when he offered up himself.
–Hebrews 7:23-27
