Hebrews 5:1-4

For every High Priest was chosen from among the people and appointed to represent them before God by presenting their gifts to God and offering sacrifices on their behalf. Since the High Priest is also one who is clothed in weakness, he humbles himself by showing compassion to those who are ignorant of God’s ways and stray from them. And for this reason, he has to not only present the sin offerings of others, but also to bring a sin offering for himself. And no one takes this honor upon himself by being self-appointed, but God is the one who calls each one, just as Aaron was called.
