Revelation 5:5; Revelation 22:16

5 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.
16 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.
