'Particular' in the Bible

You must not do any work on this particular day, because it is a day of atonement to make atonement for yourselves before the Lord your God.

Indeed, any person who does not behave with humility on this particular day will be cut off from his people.

As for any person who does any work on this particular day, I will exterminate that person from the midst of his people!

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.
