Revelation 5:2-6
  
5:2 And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof?
5:3 And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon.
5:4 And I wept much, because no man was found worthy to open and to read the book, neither to look thereon.
5:5 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.
5:6 And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth.
