At the time when the angel clothed in linen spoke to Daniel, none of the events in this vision had happened. This definitely refers to the the events in [Daniel 12:1-4](./01.md), and may possibly also include the events in the vision from chapter 11.
The vision that was given to Daniel was not to be explained. The book was sealed and no one could access it. AT: "for you are to close up and seal the words you have written" (See: [[rc://en/ta/man/translate/figs-metaphor]])
