'Sealed' in the Bible

Then the king's scribes were called in on the first month, on the thirteenth day of the month; and all that Haman commanded was written to the king's satraps, and to the governors who were over every province, and to the princes of every people, to every province according its writing, and to every people in their language. It was written in the name of King Ahasuerus, and it was sealed with the king's ring.

Write also to the Jews, as it pleases you, in the king's name, and seal it with the king's ring; for the writing which is written in the king's name, and sealed with the king's ring, may not be reversed by any man."

He wrote in the name of King Ahasuerus, and sealed it with the king's ring, and sent letters by courier on horseback, riding on royal horses that were bread from swift steeds.
