Revelation 5:2 (KJV)

And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals.

And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon.

And I wept much, because no man was found worthy to open and to read the book, neither to look thereon.

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.

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.

And he came and took the book out of the right hand of him that sat upon the throne.
