The Great "O" Antiphons: December 19 - O Root of Jesse

The Great “O” Antiphons were sung before and after the Psalm at Vespers during the last seven days of Advent.  They were used to create the hymn “O Come, O Come, Emmanuel,” which is the Hymn of the Day for the Fourth Sunday in Advent: Rorate Coeli. The “O” Antiphon for December 19 is:

O Root of Jesse, standing as an ensign before the peoples, before whom all kings are mute, to whom the nations will do homage:

Come quickly to deliver us.
