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.
“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.” ~Isaiah 22:22
“And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven.” ~Matthew 16:19
“And to the angel of the church of Philadelphia, write: These things saith the Holy One and the true one, he that hath the key of David; he that openeth, and no man shutteth; shutteth, and no man openeth:
I know thy works. Behold, I have given before thee a door opened, which no man can shut: because thou hast a little strength, and hast kept my word, and hast not denied my name.” ~Revelation 3:7-8
