וַיֹּ֤אמֶר הָמָן֙ לַמֶּ֣לֶךְ אֲחַשְׁוֵר֔וֹשׁ יֶשְׁנ֣וֹ עַם־אֶחָ֗ד מְפֻזָּ֤ר וּמְפֹרָד֙ בֵּ֣ין הָֽעַמִּ֔ים בְּכֹ֖ל מְדִינ֣וֹת מַלְכוּתֶ֑ךָ וְדָתֵיהֶ֞ם שֹׁנ֣וֹת מִכָּל־עָ֗ם וְאֶת־דָּתֵ֤י הַמֶּ֙לֶךְ֙ אֵינָ֣ם עֹשִׂ֔ים וְלַמֶּ֥לֶךְ אֵין־שֹׁוֶ֖ה לְהַנִּיחָֽם׃
하만이 아하수에로 왕에게 아뢰되 한 민족이 왕의 나라 각 도 백성 중에 흩어져 거하는데 그 법률이 만민보다 달라서 왕의 법률을 지키지 아니하오니 용납하는 것이 왕에게 무익하나이다
Tze'enah Ure'enah
“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.
