Esther 8:9 (ESV)

9 The king’s scribes were summoned at that time, in the third month, which is the month of Sivan, on the twenty-third day. And an edict was written, according to all that Mordecai commanded concerning the Jews, to the satraps and the governors and the officials of the provinces from India to Ethiopia, 127 provinces, to each province in its own script and to each people in its own language, and also to the Jews in their script and their language.

The news of Haman’s death would not have reached all the corners of the empire yet. Besides, Haman’s death did not erase the edict that he had issued. His edict also contained a powerful incentive: everyone who took part in the killing of the Jews on the thirteenth of Adar, could enrich themselves with the possessions of the Jews (Esther 3:13).

Therefore, Mordecai wasted no time in acting. He immediately ordered a new edict to be written. This time, the edict was addressed in the first place to the Jews. (This fact suggests that the Jews, even those living outside of Jerusalem, had formed their own communities all over the Persian Empire.) It was written in their language and script: Hebrew, or perhaps Aramaic.

The edict was also written and sent to the Persian authorities who lived across the empire. Just as Haman’s edict (Esther 3:12), it was written in all the languages and scripts of each province.
