Esther 3:13-15 - Dispatches were sent by couriers to all the king’s provinces with the order to destroy, kill and annihilate all the Jews—young and old, women and children—on a single day, the thirteenth day of the twelfth month, the month of Adar, and to plunder their goods.
A copy of the text of the edict was to be issued as law in every province and made known to the people of every nationality so they would be ready for that day.
