MORDECAI, Sylvester Hassell Mordecai was a man of wisdom and integrity, and although a captive, was faithful to his king. During the first year of Queen Esther he discovered a plot made by two of the king’s chamberlains to murder their royal master, and upon his making it known to the queen, the conspirators were hanged. The king commanded his prime minister Haman to dress up Mordecai in the royal apparel, place him on the king’s horse, lead the horse through the streets of the city, and proclaim to the multitude the honor thus conferred on Mordecai. This was done at the very time that Haman was about to obtain the King of Persia’s permission to hang Mordecai on a gallows fifty cubits high, that he had made for that purpose, because Mordecai rose not up when Haman approached him, nor did him reverence.
But the king, on learning that Haman was the author of the decree to have all the Jews in his empire destroyed, for the offence of Haman, ordered Haman to be hanged on the gallows which he had made for Mordecai. He also virtually reversed the decree which had been made against the Jews, and authorized them to slay their enemies on the very day that they were to have been slain by them, and made Mordecai prime minister in the place of Haman.
Thus we see that in the days of Ahashuerus there were a queen and a prime minister at court of the Jewish race, and, of course, friends of the Jews (From B.C. 458 to B.C. 446).” (Hassell’s History pg 157)
