'Seal' in the Bible

“Seventy weeks have been decreed for your people and your holy city, to finish the transgression, to make an end of sin, to make atonement for iniquity, to bring in everlasting righteousness, to seal up vision and prophecy and to anoint the most holy place.

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.”
