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.
If you can get over the cryptic stuff then it is about allowing the Key of David (Jesus) to open the very depth of your life. And to free yourself from the prisons of your own making.
O Key of David, and Sceptre of the house of Israel,
that openeth and no man shutteth, and shutteth and no man openeth,
come to liberate the prisoner from the prison, and them that sit in darkness, and in the shadow of death.
Sounds good to me!
