Bo - Conversation with Moshiach What does Hashem mean when he tells Moshe and the Jewish people that "This month [Nissan] is yours?" Why do the Jewish people respond to Moshe's announcement of the impending redemption with reasons why they should not be redeemed? What is behind Hashem's response, which is that He does not calculate things like them, that He looks at the good deeds of the righteous, and that He 'skips over' the Jewish people's sins of idolatry? How does this parallel the conversation the Jewish people will have with Moshiach when he arrives and announces that the final redemption is imminent?
