At Lauds on Sunday, let the 66th psalm be said first simply, without an antiphon.
After that let the 50th psalm be said with Alleluia; after this let the 117th and the 62d be said; then the blessing and the praises, one lesson from the Apocalypse, said by heart, a responsory, the Ambrosian hymn, the verse and the canticle from the Gospel, the litany, and it is finished.
Chap. 12
All scripture is given by inspiration of God and is profitable for doctrine, reproof, correction, and instruction in righteousness (2 Timothy 3:16).
