'Groups' in the Bible

And Haman said to King Ahasuerus, There is a certain nation living here and there in small groups among the people in all the divisions of your kingdom; their laws are different from those of any other nation, and they do not keep the king's laws: for this reason it is not right for the king to let them be.

In every province and every city, wherever the king’s command and his law reached, joy and rejoicing took place among the Jews. There was a celebration and a holiday. And many of the ethnic groups of the land professed themselves to be Jews because fear of the Jews had overcome them.
