(M279) In the first place, the feast of Purim was and is held on the fourteenth and fifteenth days of Adar, the last month of the Jewish year, which corresponds roughly to March.(825) Thus the date agrees nearly, though not exactly, with the date of the Babylonian Zakmuk, which fell a fortnight later in the early days of the following month Nisan. A trace of the original celebration of Purim in Nisan may perhaps be found in the statement that “they cast Pur, that is, the lot, before Haman” in Nisan, the first month of the year.(826) It has been suggested with some plausibility that the Jews may have shifted the date of Purim in order that the new and foreign festival might not clash with their own old festival of the Passover, which began on the fourteenth day of Nisan. Another circumstance which speaks at once for the alien origin of Purim and for its identity with Zakmuk is its name. The author of the book of Esther derives the name Purim from _pur_, “a lot,”(827) but no such word with this signification exists in Hebrew, and hence we are driven to look for the meaning and etymology of Purim in some other language. A specious theory is that the name was derived from an Assyrian word _puvru_, “an assembly,” and referred primarily to the great assembly of the gods which, as we have seen, formed a chief feature of the festival of Zakmuk, and was held annually in the temple of Marduk at Babylon for the purpose of determining the fates or lots of the new year;(828) the august assembly appears to have been occasionally, if not regularly, designated by the very name _puvru_.(829) On this hypothesis the traditional Jewish explanation of the name Purim preserved a genuine kernel of historical truth, or at least of mythical fancy, under the husk of a verbal error; for the name, if this derivation of it is correct, really signified, not “the lots,” but the assembly for drawing or otherwise determining the lots. Another explanation which has been offered is “that _pūr_ or _būr_ seems to be an old Assyrian word for ‘stone,’ and that therefore it is possible that the word was also used to signify ‘lot,’ like the Hebrew גורל ‘lot,’ which originally, no doubt, meant ‘little stone.’ ”(830) Either of these explanations of the name Purim, by tracing it back to the New Year assembly of the gods at Babylon for settling the lots, furnishes an adequate explanation of the traditional association of Purim with the casting of lots—an association all the more remarkable and all the more likely to be ancient because there is nothing to justify it either in the Hebrew language or in the Jewish mode of celebrating the festival. When to this we add the joyous, nay, extravagant festivity which has always been characteristic of Purim, and is entirely in keeping with a New Year celebration, we may perhaps be thought to have made out a fairly probable case for holding that the Jewish feast is derived from the Babylonian New Year festival of Zakmuk.
