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.
O Key of David, and scepter of the house of Israel, who opens and no man shuts, who shuts and no man opens: come, and lead forth the captive who sits in the shadows from his prison.
Isaias 22:22
And I will lay the key of the house of David upon his shoulder: and he shall open, and none shall shut: and he shall shut, and none shall open.
Isaias 9:6
For a child is born to us, and a son is given to us, and the government is upon his shoulder: and his name shall be called Wonderful, Counsellor, God the Mighty, the Father of the world to come, the Prince of Peace.
