The book that Daniel sealed appears to be the same book that Jesus Christ takes and breaks the seven seals. Daniel was told to shut up the words and seal the book until the time of the end.
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. (Daniel 12:4)
When he asked: “how long shall it be to the end of these wonders?” he was told for 3.5 years until Antichrist scatters the power of the holy people.
And [one] said to the man clothed in linen, which [was] upon the waters of the river, How long [shall it be to] the end of these wonders? And I heard the man clothed in linen, which [was] upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that [it shall be] for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these [things] shall be finished. (Daniel 12:6-7)
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. (Revelation 5:1)
John refers to the woman in heaven and the great red dragon as “wonders” that last for 3.5 years.
