'Seal' in the Bible

A stone was brought and placed over the opening to the pit, and the king affixed a seal to it with his personal signet ring and with the signet rings of his officials so that no one would interfere with Daniel's situation.

The vision of the evenings and the morningsthat has been told is true.Now you must seal up the visionbecause it refers to many days in the 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.

After some years they will form an alliance, and the daughter of the king of the South will go to the king of the North to seal the agreement. She will not retain power, and his strength will not endure. She will be given up, together with her entourage, her father, and the one who supported her during those times.

But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.
