'First' in the Bible

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

In the first month, that 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, that is, the month Adar.

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