O Key of David: once that key unlocks us, we're free forever!

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


O Key of David,
and scepter of the house of Israel,
You open, and no man shuts,
You shut, and no man opens:
come, and lead the captive from the prison house,
who sits in darkness and the shadow of death.
