Introit Isa. 45 Rorate, caeli, désuper, et nubes pluant justum: aperiátur terra, et gérminet Salvatórem. V. ibid. Et justitia oriátur simul; ego Dóminus creávi eum. Gloria Patri... Rorate. (The introit of the 4th Sunday of Advent.)
Introit. Isa. 45 Drop down dew, ye heavens, from above, and let the clouds rain the Just One: let the earth be opened, and bud forth a Savior. V. And let justice spring up together: I the Lord have created him. Glory be... Drop down.
Note that in this recording, the Dominicans sing the introit not with the first verse of Psalm 18, as is found in the Roman Missal, but with the rest of the verse of Isaiah (45, 8.) This was a common practice with this particular introit in the Middle Ages, and is also found, e.g., in the Sarum Use.
Since it is the 21st of December, the following O Antiphon is sung at Vespers.
O Oriens, splendor lucis aeternae, et sol justitiae: veni, et illumina sedentes in tenebris, et umbra mortis.
