Revelation 1:18; Revelation 3:7; Revelation 9:1; Revelation 20:1
I am he that liveth , and was dead; and, behold , I am alive for evermore , Amen; and have the keys of hell and of death.
And to the angel of the church in Philadelphia write ; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth , and no man shutteth ; and shutteth , and no man openeth ;
And the fifth angel sounded , and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
