'Seal Up' in the Bible

The vision of the evenings and mornings which has been told is true; but seal up the vision because it refers to many days from now."

Seventy weeks are decreed on your people and on your holy city, to put an end to the transgression, and to make an end to sin, and to atone for iniquity, and to bring in everlasting righteousness, and to seal up vision and prophecy, and to anoint the most holy place.
