[101] May I not call the restoration of a deposit a useful plant of the soul? But still this plant requires purification and exceeding attention. What then is the purification? This. Having taken a deposit from a man while he is sober, you must not restore it to him while he is drunk, or intemperate, or mad; for in such a case though he may have received the advantage of having his own back again, he will have no opportunity of being benefited by it. Again. You must not restore a deposit to debtors or to slaves while their creditors or their masters are present; for that is betraying, and not a restoration of a deposit. Nor must you keep faith in small things in the hope merely of gaining confidence, so as to have greater things entrusted to you.
