Latin:

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.

“I will place on his shoulder the key to the house of David; what he opens no one can shut, and what he shuts no one can open.”

Isaiah 22:22 (NIV)

“Of the greatness of his government and peace there will be no end.
He will reign on David’s throne and over his kingdom, establishing and upholding it with justice and righteousness from that time on and forever. The zeal of the Lord Almighty will accomplish this.”

Isaiah 9:7 (NIV)

“…to open eyes that are blind, to free captives from prison and to release from the dungeon those who sit in darkness.

Isaiah 42:7
