Esther 9:32

And the decree of Esther confirmed these matters of Purim; and it was written in the book, that which related the events connected with the establishment of the festival. The Feast of Esther, or that of Purim, is celebrated by the Jews to this day. "On both days of the feast the modern Jews read over the Megillah, or Book of Esther, in their synagogues. The copy read must not be printed, but written on vellum in the form of a roll; and the names of the ten sons of Haman are written on it in a peculiar manner, being ranged, they say, like so many bodies on a gibbet. The reader must pronounce all these names in one breath. Whenever Haman's name is pronounced, they make a terrible noise in the synagogue. Some drum with their feet on the floor, and the boys have mallets with which they knock and make a noise. They prepare themselves for their carnival by a previous fast, which should continue three days, in imitation of Esther's; but they have mostly reduced it to one day. " It is perfectly right and proper that Christians celebrate also such festivals on which they remember some great teacher of the Church and the great things which the Lord did through such a chosen instrument of His grace, as in the case of Martin Luther.
