And the vision of the evening and the morning which was told is true: wherefore shut thou up the vision; for it shall be for many days.
Shut thou up the vision - implying the vision was not to be understood for the present. In Revelation 13:10 it is said, "Seal not the vision, for the time is at hand." What in Daniel's time was hidden, was more fully explained in Revelation, and as the time draws nearer it will be clearer still.
For it shall be for many days - it refers to remote times (Ezekiel 12:27).
