Hebrews 5:2-4

New Revised Standard Version, Anglicised Catholic Edition

² He is able to deal gently with the ignorant and wayward, since he himself is subject to weakness; ³ and because of this he must offer sacrifice for his own sins as well as for those of the people. ⁴ And one does not presume to take this honour, but takes it only when called by God, just as Aaron was.
