Revelation 3:7-8

ABU^{(i) 7} And to the angel of the church in Philadelphia write: These things says the Holy, the True, he who has the key of David, he who opens, and no one shall shut, and shuts, and no one opens. ⁸ I know thy works. Behold, I have set before thee a door opened, which no one can shut; because thou hast little power and didst keep my word, and didst not deny my name.
