Then King Ahasuerus said to Queen Esther and to the Jew Mordecai, "See, I have given Esther the house of Haman, and they have hanged him on the gallows, because he plotted to lay hands on the Jews.
You may write as you please with regard to the Jews, in the name of the king, and seal it with the king's ring; for an edict written in the name of the king and sealed with the king's ring cannot be revoked."
The king's secretaries 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, to the Jews and to the satraps and the governors and the officials of the provinces from India to Ethiopia, one hundred twenty-seven provinces, to every province in its own script and to every people in its own language, and also to the Jews in their script and their language.

By these letters the king allowed the Jews who were in every city to assemble and defend their lives, to destroy, to kill, and to annihilate any armed force of any people or province that might attack them, with their children and women, and to plunder their goods
on a single day throughout all the provinces of King Ahasuerus, on the thirteenth day of the twelfth month, which is the month of Adar.
A copy of the writ was to be issued as a decree in every province and published to all peoples, and the Jews were to be ready on that day to take revenge on their enemies.
So the couriers, mounted on their swift royal steeds, hurried out, urged by the king's command. The decree was issued in the citadel of Susa.
Then Mordecai went out from the presence of the king, wearing royal robes of blue and white, with a great golden crown and a mantle of fine linen and purple, while the city of Susa shouted and rejoiced.
For the Jews there was light and gladness, joy and honor.
In every province and in every city, wherever the king's command and his edict came, there was gladness and joy among the Jews, a festival and a holiday. Furthermore, many of the peoples of the country professed to be Jews, because the fear of the Jews had fallen upon them.
