'Particular' in the Bible

Then Haman said to King Ahasuerus, "There is a particular people that is dispersed and spread among the inhabitants throughout all the provinces of your kingdom whose laws differ from those of all other peoples. Furthermore, they do not observe the king's laws. It is not appropriate for the king to provide a haven for them.

Letters were sent by the runners to all the king's provinces stating that they should destroy, kill, and annihilate all the Jews, from youth to elderly, both women and children, on a particular day, namely the thirteenth day of the twelfth month (that is, the month of Adar), and to loot and plunder their possessions.
