O Key of David/O Clavis David

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.

Latin: 
O Clavis David, et sceptrum domus Israel: qui aperis, et nemo claudit; claudis, et nemo aperit: veni, et educ vinctum de domo carceris, sendentem in tenebris.

Relevant Verse from O Come, O Come Emmanuel:
O come, thou Key of David, come,
And open wide our heavenly home;
Make safe the way that leads on high,
And close the path to misery.

References in Scripture:
Isaiah 22:22
Revelation 3:7

So have you learned any new Latin words? Or enjoyed finding any derivatives? English derivatives are words that derive their roots from Latin. For example (from above): See the word "domus?"  From the context we can see that "domus" means "house," right? A derivative of the word "domus" would be "domestic", as in having to do with the home.
