Hebrews 5:2

1For 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:

2Who can have compassion on the ignorant, and on them that are out of the way; for that he himself also is compassed with infirmity.

3And by reason hereof he ought, as for the people, so also for himself, to offer for sins.

4And no man taketh this honour unto himself, but he that is called of God, as was Aaron.
