Hillel's understanding of this verse serves as the source for his original and our mimetic practice of eating matzo and marror together. In truth, the dialectical merging of the symbols for redemption and servitude occurs within the mitzvah of matzo itself. Not only is matzo the quintessential symbol of redemption, but simultaneously it evokes images of suffering and slavery. Upon reflection, this apparent anomaly points us to a profound, enhanced understanding of the relationship between suffering and redemption within Hashem's providential scheme.
Redemption is an outgrowth rather than a reversal of suffering.
Accordingly, matzo simultaneously symbolizes both suffering and redemption. Moreover, matzo and marror merge because in Hashem's master providential plan suffering forges redemption. Bnei Yisroel emerged from the iron furnace of Egypt poised to become an unique nation, the chosen people. This perspective on the relationship between suffering and redemption has sustained and nourished Kelal Yisroel throughout the generations. May it continue to sustain and nourish us, individually and collectively, until the coming of Moshiach, bimherah be-yamenu, amen.
