Chapter 42: That after "completorium" no one shall speak
At all times the monks ought to practise silence, but most of all in the nocturnal hours. And thus at all times, whether of fasting or of eating: if it be meal-time, as soon as they have risen from the table, all shall sit together and one shall read selections or lives of the Fathers, or indeed anything which will edify the hearers. But not the Pentateuch or Kings; for, to weak intellects, it will be of no use at that hour to hear this part of Scripture; but they shall be read at other times. But if the days are fast days, when Vespers have been said, after a short interval they shall come to the reading of the selections as we have said; and four or five pages, or as much as the hour permits having been read, they shall all congregate, upon the cessation of the reading. If, by chance, any one is occupied in a task assigned to him, he shall nevertheless approach. All therefore being gathered together, they shall say the completing prayer; and, going out from the "completorium," there shall be no further opportunity for any one to say anything. But if any one be found acting contrary to this rule of silence, he shall be subjected to a very severe punishment. Unless a necessity in the shape of guests should arise, or the abbot, by chance, should give some order. But even this, indeed, he shall do most seriously, with all gravity and moderation.
