O Antiphons - Dec. 20 O Key of David

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 20 is:

O Key of David and scepter of the house of Israel, You open and no one can close, You close and no one can open:

Come and rescue the prisoners who are in darkness and the shadow of death.
