Esther 8:12-14
8:12 This was to take place on a certain day throughout all the provinces of King Ahasuerus – namely, on the thirteenth day of the twelfth month (that is, the month of Adar).
8:13 A copy of the edict was to be presented as law throughout each and every province and made known to all peoples, so that the Jews might be prepared on that
day to avenge themselves from their enemies.
8:14 The couriers who were riding the royal horses went forth with the king’s edict without delay. And the law was presented in Susa the citadel as well.
