After Haman had finished his arraignment of the Jews, God said: "Thou didst well enumerate the holidays of the Jews, yet thou didst omit the two Purim and Shushan-Purim which the Jews will celebrate to commemorate thy fall."
Clever though Haman's charge was, the vindication of the Jews was no whit less clever. For they found a defender in the archangel Michael. While Haman was delivering his indictment, he spoke thus to God: "O Lord of the world! Thou knowest well that the Jews are not accused of idolatry, nor of immoral conduct, nor of shedding blood; they are accused only of observing Thy Torah." God pacified him: "As thou livest, I have not abandoned them, I will not abandon them."
