O Oriens — the Fifth Great Antiphon
Antiphon in English: Dayspring, Brightness of the everlasting light, Sun of justice, come to give light to them that sit in darkness and in the shadow of death!
Antiphon in Latin: O Oriens, splendor lucis æternæ, et sol justitiæ: veni, et illumina sedentes in tenebris, et umbra mortis.
O Radiant Dawn, splendor of eternal light, sun of justice: come, shine on those who dwell in darkness and the shadow of death. Isaiah had prophesied, The people who walked in darkness have seen a great light; upon those who dwelt in the land of gloom a light has shown. (Isaiah 9:1).
