'Seal Up' in the Bible

“The vision of the evenings and the morningsWhich has been told [to you] is true.But keep the vision a secret,For it has to do with many days in the now distant future.”

Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.

But as for you, Daniel, conceal these words and seal up the book until the end of time; many will go back and forth, and knowledge will increase.”
