'Month' in the Bible

So Esther was taken unto king Ahasuerus into his house royal 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, they cast Pur, that is, the lot, before Haman from day to day, and from month to month, to the twelfth month , which is the month Adar.

Then were the king's scribes called in the first month, on the thirteenth day thereof; and there was written according to all that Haman commanded unto the king's satraps, and to the governors that were over every province, and to the princes of every people, to every province according to the writing thereof, and to every people after their language; in the name of king Ahasuerus was it written, and it was sealed with the king's ring.

And letters were sent by posts into all the king's provinces, to destroy, to slay, and to cause to perish, all Jews, both young and old, little children and women, in one day, even upon the thirteenth day of the twelfth month, which is the month Adar, and to take the spoil of them for a prey.

Then were the king's scribes called at that time, in the third month Sivan, on the three and twentieth day thereof; and it was written according to all that Mordecai commanded unto the Jews, and to the satraps, and the governors and princes of the provinces which are from India unto Ethiopia, a hundred twenty and seven provinces, unto every province according to the writing thereof, and unto every people after their language, and to the Jews according to their writing, and according to their language.

upon one day in all the provinces of king Ahasuerus, namely , upon the thirteenth day of the twelfth month, which is the month Adar.

Now in the twelfth month, which is the month Adar, on the thirteenth day of the same, when the king's commandment and his decree drew near to be put in execution, on the day that the enemies of the Jews hoped to have rule over them, (whereas it was turned to the contrary, that the Jews had rule over them that hated them,)

And the Jews that were in Shushan gathered themselves together on the fourteenth day also of the month Adar, and slew three hundred men in Shushan; but on the spoil they laid not their hand.

This was done on the thirteenth day of the month Adar; and on the fourteenth day of the same they rested, and made it a day of feasting and gladness.

Therefore do the Jews of the villages, that dwell in the unwalled towns, make the fourteenth day of the month Adar a day of gladness and feasting, and a good day, and of sending portions one to another.

to enjoin them that they should keep the fourteenth day of the month Adar, and the fifteenth day of the same, yearly,

as the days wherein the Jews had rest from their enemies, and the month which was turned unto them from sorrow to gladness, and from mourning into a good day; that they should make them days of feasting and gladness, and of sending portions one to another, and gifts to the poor.
