Perhaps this is really, really way off.

But I was wondering if there is even a slight, very slight, possibility that these a related to each other?

Daniel 12:4 But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.

  9 And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end.

Revelation 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.

Could the book that Daniel was told to seal, was right there for Daniel to seal, then and there, as he was told?

Or does it mean that the book that Daniel would later write, about these things, would be sealed from being read and understood, like the following?

Isaiah 29:11 And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it is sealed:

But if the book sealed in Daniel 12, is the book that Jesus opens in Revelation 5, then it is being opened at the time of the end.

Either way, the book sealed in Daniel 12, will have been opened at the time of the end.

The seven thunders that John heard are still to be sealed (until they are physically heard by those on the earth?)

So, at the final chapter of the last book of the word of God, John is told not to seal that book:

Revelation 22:10 And he saith unto me, Seal not the sayings of the prophecy of this book: for the time is at hand.
