Chapter 18, In What Order the Psalms Are to Be Said
In the beginning let there be said the verse, Deus, in adjutorium meum intende; Domine, ad adjuvandum me festina (Ps 69:2), and the Gloria, followed by the hymn for each Hour. At Prime on Sunday, then, there are to be said four sections of the 118th psalm. At the other Hours, however, namely Tierce, Sext, and None, let three sections of the same psalm be said. But at Prime on Monday let three psalms be said, namely, the first, the second, and the sixth; and thus each day at Prime until Sunday, let three psalms be said each time in consecutive order up to the 19th psalm, yet so that the ninth psalm and the 17th be each divided into two Glorias; and thus it will come about that at the night office on Sundays we always begin with the 20th psalm.
At Tierce, Sext, and None, on Monday, however, let the nine sections which remain over the 118th psalm be said, three sections at each of these Hours. The 118th psalm having thus been parceled out for two days, namely, Sunday and Monday, let there be sung on Tuesday for Tierce, Sext, and None, three psalms each, from the 119th to the 127th, that is, nine psalms. These psalms will always be repeated at the same Hours in just the same way until Sunday, observing also for all these days a regular succession of the hymns, the lessons, and the verses, so, namely, that on Sunday the beginning is always made with the 118th psalm.
Let Vespers be sung daily with the singing of four psalms. Let these psalms begin with the 109th to the 147th, excepting those which are set aside for the other Hours; namely, from the 117th to the 127th, and the 133d, and the 142d. All the rest are to be said at Vespers; and as the psalms fall three short, those of the aforesaide psalms which are found to be longer, are to be divided; namely, the 138th, the 143d, and the 144th. But because the 116th is short, let it be joined to the 115th. The order of the psalms for Vespers having thus been arranged let the rest, namely, the lessons, the responsories, the hymns, the verses, and the canticles, be said as we have directed above.
At Compline, however, let the same psalms be repeated every day; namely, the 4th, the 90th, and the 133d.
Having arranged the order of the office, let all the rest of the psalms which remain over, be divided equally into seven night offices, by so dividing such of them as are of greater length that twelve fall to each night. We especially impress this, that, if this distribution of the psalms should perchance displease anyone, he arrange them if he thinketh another better, by all means seeing to it that the whole Psalter of one hundred and fifty psalms be said every week, and that it always start again from the beginning at Matins on Sunday; because those monks show too lax a service in their devotion who in the course of a week chant less than the whole Psalter with is customary canticles; since we read, that our holy forefathers promptly fulfilled in one day what we lukewarm monks should, please God, perform at least in a week.
Chapter 19, Of the Manner of Reciting the Psalter
We believe that God is present everywhere and that the eyes of the Lord behold the good and the bad in every place (cf Prov 15:3). Let us firmly believe this, especially when we take part in the Work of God. Let us, therefore, always be mindful of what the Prophet saith, "Serve ye the Lord with fear" (Ps 2:11). And again, "Sing ye wisely" (Ps 46:8). And, "I will sing praise to Thee in the sight of the angels" (Ps 137:1). Therefore, let us consider how it becometh us to behave in the sight of God and His angels, and let us so stand to sing, that our mind may be in harmony with our voice.
Chapter 20, Of Reverence at Prayer
If we do not venture to approach men who are in power, except with humility and reverence, when we wish to ask a favor, how much must we beseech the Lord God of all things with all humility and purity of devotion? And let us be assured that it is not in many words, but in the purity of heart and tears of compunction that we are heard. For this reason prayer ought to be short and pure, unless, perhaps it is lengthened by the inspiration of divine grace. At the community exercises, however, let the prayer always be short, and the sign having been given by the Superior, let all rise together.
Chapter 21, Of the Deans of the Monastery
If the brotherhood is large, let brethren of good repute and holy life be chosen from among them and be appointed Deans; and let them take care of their deaneries in everything according to the commandments of God and the directions of their Abbot. Let such be chosen Deans as the Abbot may safely trust to share his burden. Let them not be chosen for their rank, but for the merit of their life and their wisdom and knowledge; and if any of them, puffed up with pride, should be found blameworthy and, after having been corrected once and again and even a third time, refuseth to amend, let him be deposed, and one who is worthy be placed in his stead. We make the same regulation with reference to the Prior.
Chapter 22, How the Monks Are to Sleep
Let the brethren sleep singly, each in a separate bed. Let them receive the bedding befitting their mode of life, according to the direction of their Abbot. If it can be done, let all sleep in one apartment; but if the number doth not allow it, let them sleep in tens or twenties with the seniors who have charge of them. Let a light be kept burning constantly in the cell till morning.
Let them sleep clothed and girded with cinctures or cords, that they may be always ready; but let them not have knives at their sides whilst they sleep, lest perchance the sleeping be wounded in their dreams; and the sign having been given, rising without delay, let them hasten to outstrip each other to the Work of God, yet with all gravity and decorum. Let the younger brethren not have their beds beside each other, but intermingled with the older ones; and rising to the Work of God, let them gently encourage one another on account of the excuses of the drowsy.
Chapter 23, Of Excommunication for Faults
If a brother is found stubborn or disobedient or proud or murmuring, or opposed to anything in the Holy Rule and a contemner of the commandments of his Superiors, let him be admonished by his Superiors once and again in secret, according to the command of our Lord (cf Mt 18:15-16). If he doth not amend let him be taken to task publicly before all. But if he doth not reform even then, and he understandeth what a penalty it is, let him be placed under excommunication; but if even then he remaineth obstinate let him undergo corporal punishment.
