'First' in the Bible

and the next to 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, and chose the twelfth month, which is the month Adar.

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