O Key of David, and Scepter of the House of Israel, who opens and no man shuts, who shuts and no man opens; Come and bring forth the captive from his prison, he who sits in darkness and in the shadow of death.
O Clavis David, et sceptrum domus Israel, qui aperis, et nemo claudit, claudis, et nemo aperuit: veni, et educ vinctum de domo carceris, sedentem in tenebirs, et umbra mortis.
"O Antiphon" for December 20th
Christ Giving the Keys to St. Peter
As sung by the Dominican student brothers in Oxford
