CHAPTER IX. How many Psalms are to be said at the Night Hours

11 Feb. 12 June. 12 Oct.

In winter time, after beginning with the verse, “O God, come to my assistance; O Lord, make haste to help me,” with the Gloria, let the words, “O Lord, Thou wilt open my lips, and my mouth shall declare Thy praise,” be next repeated thrice; then the third Psalm, with a Gloria, after which the ninety-fourth Psalm is to be said or sung, with an antiphon. Next let a hymn follow, and then six Psalms with antiphons. These being said, and also a versicle, let the Abbot give the blessing and, all being seated, let three lessons be read by the brethren in turns, from the book on the lectern. Between the lessons let three responsories be sung - two of them without a Gloria, but after the third let the reader say the Gloria: and as soon as he begins it, let all rise from their seats out of honour and reverence to the Holy Trinity. Let the divinely inspired books, both of the Old and New Testaments, be read at the Night-Office, and also the commentaries upon them written by the most renowned, orthodox and Catholic Fathers. After these three lessons with their responsories, let six more Psalms follow, to be sung with an Alleluia. Then let a lesson from the Apostle be said by heart, with a verse and the petition of the Litany, that is, Kyrie eleison. And so let the Night-Office come to an end.
