ציטירנדיקער פּירוש אויף אסתר 5:12

אף כי אמר אלוקים, “did G-d really say, etc.?” The very first word the serpent uttered was the word אף. Our sages in Bereshit Rabbah 19,2 commented on this: “four people began their remarks with the word אף, and all four of them perished through אף, divine anger. The four are: the serpent, the chief of the bakers (Genesis 40,16), the community who partook in Korach’s uprising (Numbers 16,14) and Haman (Esther 5,12).
