O Clavis David,et sceptrum domus Israël,qui aperis, et nemo claudit, claudis, et nemo aperuit: veni, et educ vinctumde domo carceris,sedentem in tenebris,et umbra mortis.O Key of David and scepter of the house of Israel, you open and no one can close, you close and no one can open: Come and rescue the prisoners who are in darkness and the shadow of death.
