The Rule of St. Benedict - Chapter 31. Qualifications Of The Monastery Cellarer

(13) Above all, let him be humble. If goods are not available to meet a request, he will offer a kind word in reply,
(14) for it is written: A kind, "word is better than the best gift," (Sir 18:17).
(15) He should take care of all that the abbot entrusts to him, and not presume to do what the abbot has forbidden.
(16) He will provide the brothers their allotted amount of food without any pride or delay, lest they be led astray. For he must remember what the Scripture says that person deserves, "who leads one of the little ones astray," (Matt 18:6).

(17) If the community is rather large, he should be given helpers, that with their assistance he may calmly perform the duties of his office.
(18) Necessary items are to be requested and given at the proper times,
(19) so that no one may be disquieted or distressed in the house of God.
