Hebrews 5:1-4

Every high priest is chosen from among other people. He is given the work of going before God for them to offer gifts and sacrifices for sins. Since he himself is weak, he is able to be gentle with those who do not understand and who are doing wrong things. Because he is weak, the high priest must offer sacrifices for his own sins and also for the sins of the people. To be a high priest is an honor, but no one chooses himself for this work. He must be called by God as Aaron was.
