Revelation 3:7; Revelation 5:5; Revelation 22:16
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 one of the elders saith unto me, Weep not: behold , the Lion of the tribe of Juda, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.
I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
