...okay so - when we last left our heroes The Almighty had instructed Moshe to present himself to the King of Egypt as His messenger and request a three day escape into the wilderness for Bnei Yisroel to pray/sacrifice to G-D. This week the request is denied in triplicate and all manner of makkos ensues.
The thing is...Three Days? Really? Is that what the plan was? As best I recall when the nation ends up leaving they don't plan on coming back. So what's the deal? Is there a grand lie/subterfuge going on here? And if so why? (Also, why at some point does the request change to the more common "let my people go", as in forever?)
