Esth 9:10

“The ten sons of Haman I saw in Seder Olam (ch. 29): These are the ten who wrote a [false] accusation against Judea and Jerusalem, as it is written in the Book of Ezra (4:6): “And in the reign of Ahasuerus, at the beginning of his reign, they wrote an accusation against the dwellers of Judea and Jerusalem.” Now what was the accusation? To stop those who ascended from the exile during the days of Cyrus, who had commenced to build the Temple, and the Cutheans slandered them and stopped them, and when Cyrus died, and Ahasuerus reigned, and Haman was promoted, he feared that those in Jerusalem would engage in the construction, and they sent in the name of Ahasuerus to the princes of the other side of the river to stop them. but on the spoil they did not lay their hands so that the king should not cast an envious eye on their money.”

“The ten sons of Haman - Their names are given above. And it is remarked here, and in Est 9:16, where the account is given of the number slain in the provinces, that the Jews laid no hands on the spoil. They stood for their lives, and gave full proof that they sought their own personal safety, and not the property of their enemies, though the decree in their favor gave them authority to take the property of all those who were their adversaries, Est 8:11.”
