EST 3:12

12 Then the king's scribes were summoned on the thirteenth day of the first month, and a decree containing all that Haman had commanded was written to the king's provincial governors, those who were over all the provinces, to the governors of all the various peoples, and to the officials of all the people, to every province in their own writing, and to every people in their own language. It was written in the name of King Ahasuerus and was sealed with his ring.
