Following the initial day of battle and the king's report on the resulting casualties, Queen Esther seizes a moment of royal goodwill to secure a lasting victory. She requests an extension of the defense decree for an additional day within the capital, alongside the public hanging of Haman's ten sons. This request is a calculated strategy to complete the mission on physical, spiritual, and psychological fronts.
Esther recognized that a significant number of enemies, particularly the core leaders of Amalekite descent, were still alive. During the initial fighting, the Jews had held back out of fear of the local authorities and did not dare to completely eliminate their attackers [רלב״ג, יוסף אבן יחיא, עמנואל הרומי]. Furthermore, the battlefield was shifting. While the first day's clashes occurred primarily around the palace grounds, Esther now sought permission to fight within the city itself. She anticipated that as the Jews returned to their neighborhoods, the grieving relatives of the defeated enemies would seek violent revenge. To survive, the Jews needed explicit legal backing—essentially a direct verbal order from the king—to continue defending themselves in the city streets [מלבי״ם, מנות הלוי, ביאור שטיינזלץ].
On a spiritual level, Esther noticed that the divine presence, which had previously rested in the capital due to the high court and Mordecai's leadership, had departed when the decree of annihilation was issued. She understood that this holiness could not return until the impurity of their enemies was entirely uprooted, making an additional day necessary to purify the city [מגילת סתרים]. She also sought to capitalize on the month of Adar, a time when the fortune of the Israelites is especially strong, to completely dismantle Haman's plot and achieve a victory that united their physical survival with their spiritual devotion to the Torah [מנות הלוי, מחיר יין].
Regarding the request to hang Haman's ten sons, the primary approach among commentators is that these men had already been killed in the earlier battles, and Esther was asking to publicly display their corpses. However, another perspective suggests they were only mortally wounded by the sword, and she wished to hang them in their final moments before death [מנות הלוי]. The purpose of this public display was twofold. First, it served as a powerful visual confirmation that the king fully supported the Jews' actions, branding the dead men as rebellious criminals rather than victims of random street violence [ביאור שטיינזלץ]. Second, the display was designed to strike terror into the hearts of any remaining enemies, deterring future attacks while casting an eternal disgrace upon Haman's lineage [מלבי״ם, רלב״ג, יוסף אבן יחיא]. Ultimately, the ten sons were not hung on separate gallows, but were all suspended together on the very same tall, recognizable structure where their father had met his end [אבן עזרא].
