Alexander McLeod's Messiah, Governor of the Nations of the Earth: 'Similar to this vision with which Daniel was favoured while captive in Babylon, was the representation made to John the apostle, while in his banishment in Patmos. Revelation 5:1-2, 5, 7. And I saw in the right hand of him that sat on the throne a book, written within, and on the back side sealed with seven seals. And I saw a strong angel, proclaiming with a loud voice, Who is worthy to open the book and to loose the seals thereof. And one of the elders saith unto me, Weep not: behold the lion of the tribe of Judah, the root of David, hath prevailed to open the book, and to loose the seals thereof. And he came and took the book out of the right hand of him that sat upon the throne. The purposes of the divine mind, like a sealed book, remain to be unfolded and executed. These decrees, and the right to execute them, are Jehovah's. The book is in his hand who sits on the throne. God seeks an actual administrator of his purposes. Proclamation is made, Who is worthy to open the book? Messiah, amidst the approving shouts of innumerable intelligences, approaches the throne, and receives the important appointment. The Lamb slain, the Lion of the tribe of Judah, receives the book, and looses all its seals. Who shall refuse to acknowledge thee, O Jesus, as Prince of the kings of this earth?'
