Today’s Jesse Tree devotion and O Antiphon celebrates Jesus as the Radiant Dawn: Psalm 19:6-7

It comes forth like a bridegroom from his canopy,
and like a hero joyfully runs its course.

From one end of the heavens it comes forth;
its course runs through to the other;
nothing escapes its heat.

O Oriens: “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.” (9:1).
