In a rather enigmatic comment, Rashi writes, “evil, hatred, and vengeance were decided.” Haman must have known that all negative things were being focused in his direction.
The Brisker Rav asks how Haman knew that evil was decided. He answers that the Targum translates Achashverosh’s asking (Esther 7:5) “ay zeh” as “where is he.” In other words, the decision to punish whoever was responsible for this evil decree was final, and only required the finding of the culprit.
The Ben Ish Chai answers that Haman knew bad things were in store for him because he had already been advised by his friends (Esther 6:13) that his situation was deteriorating. Besides that, Haman thought that his situation would regress because Zeresh and his advisers thereby made what the Talmud (Kesubos 8b) calls “an opening for the Satan,” – saying something that could allow the Heavenly accuser an opportunity to punish someone.
The Dena Pishra answered that the verse, once again, used the word melech to refer to the King, H-Shem, because Haman angered Him, and now was certain the time had come for retribution.
Both the Dena Pishra and R’ Moshe David Valle note that the last letters of the phrase “ki chalasa eilav hara” (“because he saw that evil was decided on him”) spell out H-Sem’s Name in order. As the Chida and Rabbeinu Bachya write, when H-Shem’s Name is encoded in order, it represents His quality of mercy. This hints to the fact that Haman must have realized that all comes from H-Shem.
Parenthetically,this fact does not automatically define him as righteous righteous. After all, instead of getting on his knees at this point in true repentance to H-Shem, he begs for his life from an earthly queen. However, perhaps his begging Esther for his life instead of Achashverosh indicates that he acknowledges her righteousness, and its accompanying power. This very act may be the one that earned him the merit of having descendants who the Talmud (Sanhedrin 96b) says learn Torah in Bnei Brak learn Torah.
According to R’ Eliezer of Worms, the verse use the word “parashas” (“chapter”) to describe Haman’s meeting with Achashverosh in order to emphasize that this event was not just talk – a financial exchange took place, giving the event legal significance and legally binding consequences.
In fact, as the Divrei Shaul points out, Mordechai was communicating to Esther the fact that Achashverosh could not be easily bought off, since Haman had already given/ offered him money (see above 3:11).
As R’ Dovid Feinstein notes, Achashverosh’s refusal to accept the bribe only stresses the ferocity of his hate for the Jews, making this a very serious threat to Jewish existence, indeed. Convincing Achashverosh to change his mind would require nothing short of a miracle.
Parenthetically, According to Yaaros Dvash, the fact that Achashverosh refused the money was covered up by Haman in an attempt to deny people the opportunity to intercede on behalf of the Jews.
The Chasam Sofer writes that Mordechai’s giving the details of this entire episode here served a vital purpose later. In fact, Esther uses this event in detail to convince the king to save the Jews from Haman’s decree. In the Chasam Sofer’s view of the events, Achashverosh refused Haman’s money (see 3:11 above) because he reasoned that killing such a people was a worthwhile responsibility of his, and taking payment for this would be unethical. In Achashverosh’s mind, Haman’s offer and and his refusal were secret. Since Mordechai’s knowledge of this came through a Ruach HaKodesh-like dream, Mordechai kept the information under wraps to be used later, if necessary. Once Esther tells Achashverosh that her people had been “sold” (see 7:4 below), Achashverosh begins to suspect that Haman had libelously spread the rumor that he had, indeed, accepted Haman’s payment. Therefore, he responds by asking who would do such a thing (see 7:5 below). It seems improbable that Achashverosh had forgotten the entire incident, so he is asking who would spread such a rumor.
The Brisker Rav interprets the word “parasha” as being related to “lihafreesh” (“to set aside”). In his view, Mordechai was informing Esther of the money that was set aside, or designated for the purchase of killing out the Jews. Such money was legally binding, and eventually, Achashverosh’s only way out of the deal would have be to kill the “buyer” – Haman.
Alshich uses Rashi’s seemingly simple explanation that “parsha” means explanation to mean that Mordechai related all of the details of Haman’s and Achashverosh’s meeting, including the mystical interpretations for the reasons Haman had to offer 10,000 loaves of silver.
Finally, the Sfas Emes translates “parashas” to mean “sum,” emphasizing Haman’s generosity in contributing towards the kingdom. In view of the concept of “zeh l’umas zeh,” the Jews need to be generous with charity in order to counterbalance the generosity of our enemies.
