O Clavis

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 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.
