'Month' in the Bible

So Esther was taken to King Ahasuerus to his royal palace in the tenth month which is the month Tebeth, in the seventh year of his reign.

In the first month, which is the month Nisan, in the twelfth year of King Ahasuerus, Pur, that is the lot, was cast before Haman from day to day and from month to month, until the twelfth month, that is the month Adar.

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.

So the king’s scribes were called at that time in the third month (that is, the month Sivan), on the twenty-third day; and it was written according to all that Mordecai commanded to the Jews, the satraps, the governors and the princes of the provinces which extended from India to Ethiopia, 127 provinces, to every province according to its script, and to every people according to their language as well as to the Jews according to their script and their language.

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.

The Jews who were in Susa assembled also on the fourteenth day of the month Adar and killed three hundred men in Susa, but they did not lay their hands on the plunder.

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.

Therefore the Jews of the rural areas, who live in the rural towns, make the fourteenth day of the month Adar a holiday for rejoicing and feasting and sending portions of food to one another.

obliging them to celebrate the fourteenth day of the month Adar, and the fifteenth day of the same month, annually,

because on those days the Jews rid themselves of their enemies, and it was a month which was turned for them from sorrow into gladness and from mourning into a holiday; that they should make them days of feasting and rejoicing and sending portions of food to one another and gifts to the poor.
