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 (Isaiah 22:23), scepter of the house of Israel (Genesis 49:10), who open and no one may shut; who shut and no one may open: come, free from prison captive man, who lies in darkness and the shadow of death (Psalm 107: 10, 14).
