The Rule of St. Benedict - Chapter 18. The Order Of The Psalmody

(1) Each of the day hours begins with the verse, "God, come to my assistance; Lord make haste to help me," (Ps 69[70]:2), followed by "Glory be to the Father" and the appropriate hymn.


(2) Then, on Sunday at Prime, four sections of Psalm 118 are said.

(3) At the other hours, that is, at Terce, Sext and None, three sections of this psalm are said.

(4) On Monday three psalms are said at Prime: Psalm 1, 2 and 6.

(5) At Prime each day thereafter until Sunday, three psalms are said in consecutive order as far as Psalm 19. Psalms 9 and 17 are each divided into two sections.

(6) In this way, Sunday Vigils can always begin with Psalm 20.
