O Clavis David

December 20

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.

O Key of David, and Sceptre of the house of Israel,
that openeth and no man shutteth, and shutteth and no man openeth,
come to liberate the prisoner from the prison, and them that sit in darkness, and in the shadow of death.


Isaiah 22:22

I will place on his shoulder the key of the house of David;
he shall open, and no one shall shut;
he shall shut, and no one shall open.


Antiphon sung by the Dominican student brothers at Oxford.
