"O David's Key..."

O Key of David and scepter of the house of Israel, you open and no one closes, you close and no one opens: come and lead out from prison those who sit bound in darkness and in the shadow of death.

O Clavis David, et sceptrum domus Israel; qui aperis, et nemo claudit, claudis, et nemo aperit: veni, et educ vinctum de domo carceris, sedentem in tenebris, et umbra mortis.

(Verse before the gospel; antiphon for the canticle of the Blessed Virgin Mary – December 20)
