The Rule of St. Benedict - Chapter 35. Kitchen Servers Of The Week

(12) An hour before mealtime, the kitchen workers of the week should each receive a drink and some bread over and above the regular portion,
(13) so that at mealtime, they may serve their brothers without grumbling or hardship.
(14) On solemn days, however, they should wait until after the dismissal.

(15) On Sunday immediately after Lauds, those beginning as well as those completing their week of service should make a profound bow in the oratory before all and ask for their prayers.
(16) Let the server completing his week recite the verse: "Blessed are you, Lord God," who, "have helped me and comforted me," (Dan 3:52; Ps 85[86]:17).
(17) After this verse has been said three times, he receives a blessing. Then the one beginning his service follows and says: "God, come to my assistance; Lord, make haste to help me," (Ps 69[70]:2).
(18) And all repeat this verse three times. When he has received a blessing, he begins his service.
