A Tale of Two Adars, by Rav Yitzchak Etshalom
Why do we delay celebrating Purim until Adar Sheini?
The Mishna in Megila addresses the circumstance where after fully celebrating Purim, the Beit-Din decided to add another month to the year; although the Tosefta records a dissenting opinion, the Mishna rules (and such is the Halakha) that the Megila must be re-read in the "added" Adar - as well as the special Parashot that are read in Adar (Shekalim, Zakhor etc.). To wit, (virtually) all of the Mitzvot unique to Adar may only be fulfilled in Adar Sheini. We explore the Bavli and Yerushalmi's discussion of the various opinions and the rationale provided for ruling in accord with רשב"ג - that the Megila must be read in the Adar that is proximate to Nisan. We discover a curious explanation in the Yerushalmi, along with an innovative understanding of the impact of "מסמך גאולה לגאולה" - keeping the celebration of the redemption from Haman as close as possible the celebration of the Exodus.
