Let the weekly servers, an hour before the meal, receive each of them, over and above the regular allowance, a drink and some bread, in order that at the meal time they may serve their brethren without murmuring and undue hardship; but on feast days they must wait until after Mass. On Sunday, immediately after Lauds, the incoming and outgoing servers shall prostrate themselves before all the brethren in the oratory and ask for their prayers. Let the server who is ending his week say this verse: Benedictus es Domine Deus, qui adjuvasti me et consolatus es me.1 When this has been said three times and the outgoing server has received his blessing, then let the incoming server follow and say: Deus in adjutorium meum intende, Domine ad adjuvandum me festina.2 Let this too be repeated thrice by all the brethren, and having received his blessing let him enter on his week.
1Ps. lxxxv, 17 [Blessed are you, Lord God, who have helped and consoled me]
2Ps. lxix, 2 [O God, come to my assistance; Lord, make haste to help me]
