Esth 9:11

“Then said Esther, if it please the king,.... For she was all submission to his will: let it be granted to the Jews which are in Shushan; for no further did she desire the grant to be extended: to do tomorrow also according to this days decree; one Targum makes the request only that they might keep the morrow as a festival, but the other, more rightly, to do according to the decree of this day; which was, to slay as many of their enemies as rose up against them; and whereas many might flee and hide themselves, who were implacable enemies of the Jews, Esther moves for a grant that the decree might be continued for the next day, that these might be found out and slain; in which she sought the glory of divine justice, in their righteous destruction, and the peace of the people of God, and not private revenge, or to indulge malice: and let Haman's ten sons be hanged upon the gallows; on which their father was; this was deferred, though they were already slain, for their greater reproach, and for a terror to others not to injure the people of God; and it was usual with the Persians to hang persons on a gallows, or fix them to a cross, after they were dead; as Polycrates was by Oroites (i), and Bagspates by Parysatis (k). (i) Herodot. Thalia, sive, l. 3. c. 125. (k) Ctesias in Persicis, c. 58.”

“When on the same day an account was given to the king of the result of the conflict, and the number of those slain in Susa reported, he announced to Queen Esther: the Jews have slain in the citadel of Susa 500 men and the ten sons of Haman; "what have they done in the rest of the king's provinces?" i.e., if they have killed 500 men in Susa, how many may they not have slain in other parts of the kingdom? and then asked her what else she wished or required. With respect to the words, comp. Est 5:6, and Est 7:2.”
