Hebrews 5:1-4King James Version (KJV)
5 For every high priest taken from among men is ordained for men in things pertaining to God, that he may offer both gifts and sacrifices for sins:
2 Who can have compassion on the ignorant, and on them that are out of the way; for that he himself also is compassed with infirmity.
3 And by reason hereof he ought, as for the people, so also for himself, to offer for sins.
4 And no man taketh this honour unto himself, but he that is called of God, as was Aaron.
