'Seal Up' in the Bible

The vision of the evenings and mornings which has been told is true: but seal up the vision; for it belongs to many days [to come].

Seventy weeks are decreed on your people and on your holy city, to finish disobedience, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up vision and prophecy, and to anoint the most holy.
