Hebrews 7:23; Hebrews 7:27

23 There was a long succession of priests because when a priest died he could no longer serve.

27 We need a priest who doesn't have to bring daily sacrifices as those chief priests did. First they brought sacrifices for their own sins, and then they brought sacrifices for the sins of the people. Jesus brought the sacrifice for the sins of the people once and for all when he sacrificed himself.
