Hebrews 5:1-4

Every chief priest is chosen from humans to represent them in front of God, that is, to offer gifts and sacrifices for sin. The chief priest can be gentle with people who are ignorant and easily deceived, because he also has weaknesses. Because he has weaknesses, he has to offer sacrifices for his own sins in the same way that he does for the sins of his people. No one takes this honor for himself. Instead, God calls him as he called Aaron.
