For every high priest, being taken from among men, is appointed for men in things pertaining to God, that he may offer both gifts and sacrifices for sins.
The high priest can deal gently with those who are ignorant and going astray, because he himself is also surrounded with weakness.
Because of this, he must offer sacrifices for sins for the people, as well as for himself.
Nobody takes this honor on himself, but he is called by God, just like Aaron was.
