(14) Moses came down from the mountain to the people and warned the people to stay pure, and they washed their clothes...(16) On the third day, as morning dawned, there was thunder, and lightning, and a dense cloud upon the mountain, and a very loud blast of the horn; and all the people who were in the camp trembled.
(24) For Haman son of Hammedatha the Agagite, the foe of all the Jews, had plotted to destroy the Jews, and had cast pur—that is, the lot—with intent to crush and exterminate them. (25) But when [Esther] came before the king, he commanded: “With the promulgation of this decree,-b let the evil plot, which he devised against the Jews, recoil on his own head!” So they impaled him and his sons on the stake. (26) For that reason these days were named Purim, after pur. In view, then, of all the instructions in the said letter and of what they had experienced in that matter and what had befallen them, (27) the Jews undertook and irrevocably obligated themselves and their descendants, and all who might join them, to observe these two days in the manner prescribed and at the proper time each year.
