O Clavis David

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, Who openest and none shutteth, Who shuttest and none openeth: come Thou and bring forth the captive from the prison house who sitteth in darkness and in the shadow of death.
