The new Decree: 
A new decree was sent to all the provinces stating that on the 13th of Adar all the Jews had royal power to eliminate all their enemies on the 13th of Adar.
The rejoicing of the Jews:
Mordechai would walk around the city of Shushan with royal garments and the Jews in Shushan, as well as the Jews of every province, were filled with joy and delight. Many gentiles converted to Judaism upon seeing the Jews great favor in the eyes of the kingdom.
