'Thirteenth' in the Bible
Then the king’s scribes were summoned on the thirteenth day of the first month, and it was written just as Haman commanded to the king’s satraps, to the governors who were over each province and to the princes of each people, each province according to its script, each people according to its language, being written in the name of King Ahasuerus and sealed with the king’s signet ring.
Letters were sent by couriers to all the king’s provinces to destroy, to kill and to annihilate all the Jews, both young and old, women and children, in one day, the thirteenth day of the twelfth month, which is the month Adar, and to seize their possessions as plunder.
on one day in all the provinces of King Ahasuerus, the thirteenth day of the twelfth month (that is, the month Adar).
Now in the twelfth month (that is, the month Adar), on the thirteenth day when the king’s command and edict were about to be executed, on the day when the enemies of the Jews hoped to gain the mastery over them, it was turned to the contrary so that the Jews themselves gained the mastery over those who hated them.
This was done on the thirteenth day of the month Adar, and on the fourteenth day they rested and made it a day of feasting and rejoicing.
But the Jews who were in Susa assembled on the thirteenth and the fourteenth of the same month, and they rested on the fifteenth day and made it a day of feasting and rejoicing.
