Last Days of Pesach and Moshiach
It is fascinating to note that the ultimate connection of this reading to the last day of Passover began to emerge only in recent generations, in light of the teachings of the Baal Shem Tov and the chassidic masters.
The central idea is that Passover, in its essence, celebrates redemption. The beginning of Jewish redemption occurred with the exodus from Egypt; thus began the Jewish journey, a journey whose destination is the final and complete redemption. “The first days of Passover,” said the chassidic masters, “are the festival for the redemption of Egypt; the last day is the festival of the final redemption.” – Rabbi Mendal Debov
