They did not stumble into suffering by inadvertence; Moses refused dynastic gain and recorded his own faults

Nor can it be said that they fell into such hardships by thoughtlessness. For when they took up their office they foresaw these calamities, and voluntarily handed themselves over to be exercised and tormented by so many evils. Moses indeed was leader and priest of the Israelite people; yet how little he cared for himself and his own is plain from this: that he did not transmit the principate and the priesthood to his posterity, but designated his servant Joshua as leader of the people after him, and, at God's command, inaugurated his brother Aaron as priest.

And how far the sacred writers were from vain glory is plain from this: that if anything great or illustrious was done or said by them, they refer it wholly to God as received from Him; nay, in those very writings which they commend as divinely inspired they candidly note their own blemishes and defects; and if anything in them was slight and humble and without glory, they do not disguise it. Thus Moses recorded his own diffidence and the penalty of that diffidence which God imposed on him; and likewise his brother Aaron's idolatry and his sister Mary's murmurings.
