פּירוש אויף אסתר 3:8

“Haman said to King Ahasuerus: there is one nation scattered” [3:8]. One asks a question about this verse. What is the meaning of dispersed and afterwards he again says that they are separated among the nations? The explanation is that Haman was afraid to speak to the king about destroying one of his nations, since it is an honor for the king when he rules many nations. Therefore, Haman says to the king, it is a dispersed nation and they are not considered a nation. If you want to think that because they are dispersed among other nations so that they would have intermarried with other nations and the other nations will not allow Israel to be destroyed. Therefore, Haman says that they have separated themselves from other nations. They do not intermarry with other nations and they do not even eat or drink with other nations.³³B. Megillah, 13b. They have many more and different holidays than other nations. The Holy One said: you evildoer, you complain about their holidays, that they have too many and spend their money on food and drink for them. I will command another holiday for them that will be called Purim, when you will be hanged. They will be happy and will have to eat and drink for two consecutive days every day, forever. Also, when all other holidays will be abrogated in the days of the Messiah, Purim will remain forever.³⁴Yalkut Shimoni, Proverbs, Remez, 944.
