'Seal Up' in the Bible

The vision of the evenings and mornings that was told to you is correct. But you should seal up the vision, for it refers to a time many days from now."

"Seventy weeks have been determined concerning your people and your holy city to put an end to rebellion, to bring sin to completion, to atone for iniquity, to bring in perpetual righteousness, to seal up the prophetic vision, and to anoint a most holy place.
