'First' in the Bible

and the next unto him were Carshena, Shethar, Admatha, Tarshish, Meres, Marsena, and Memucan, the seven princes of Persia and Media, who saw the king's face, and sat first in the kingdom),

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.
