עַל־כֵּ֡ן קָֽרְאוּ֩ לַיָּמִ֨ים הָאֵ֤לֶּה פוּרִים֙ עַל־שֵׁ֣ם הַפּ֔וּר עַל־כֵּ֕ן עַל־כָּל־דִּבְרֵ֖י הָאִגֶּ֣רֶת הַזֹּ֑את וּמָֽה־רָא֣וּ עַל־כָּ֔כָה וּמָ֥ה הִגִּ֖יעַ אֲלֵיהֶֽם׃
무리가 부르의 이름을 좇아 이 두 날을 부림이라 하고 유다인이 이 글의 모든 말과 이 일에 보고 당한 것을 인하여
Rashi
For this reason ... because of all that is narrated in this letter. These days were designated, and therefore it [the Megillah] was written for the future generations to know.
Rashi
And what happened to them as a result. What did Achashveirosh see that he used the sacred vessels, “and what happened to them as a result,” that Satan came and danced among them and slew Vashti. What did Haman see that he became jealous of Mordechai, “and what happened to him as a result,” that they hanged him and his sons. What did Mordechai see that he did not kneel or prostate himself, and what did Esther see that she invited Haman?8Maseches Megillah 19a.
