I also saw a mighty angel proclaiming in a loud voice, "Who is worthy to open the scroll and break its seals?"
But no one in heaven or on earth or under the earth was able to open the scroll or even to look in it.
And I cried and cried because no one was found worthy to open the scroll or even to look in it.

Then one of the elders said to me, "Stop crying. Look! The Lion from the tribe of Judah, the Root of David, has been victorious so that He may open the scroll and its seven seals."
