Esther calls upon God and God softens the king's heart (so that he'd murder thousands of non-Jews). 15:3-11
The king decrees that Haman and his family shall hang; that everyone in the kingdom who wanted to kill the Jews shall be killed; that whoever refuses
to kill the people that wanted to kill Jews will be killed by sword and fire; and that everyone will celebrate the killing of the wannabe Jew killers forever. 16:10-18
