O Key of David and Sceptre of the house of Israel,
Who dost open and no man doth shut,
Who dost shut and no man doth open,
come and bring forth from his prisonhouse
the captive that sitteth in darkness and in the shadow of death.
“All power in heaven and on earth has been given to me” (Mt 28:18) – You say to us, O Key of David and Sceptre of the house of Israel.
You, the Lamb of God, were the only one worthy to open the Book and its seals (Rev 5:1-5).
