In the verse, Michah 7:15, it says "Like the days you went out of Egypt, I'll show them {lit. "him"} wonders", which simply implies that the future redemption will be similar to that of Egypt
The question is why does it says "like the days you went out of Egypt", if the actual event of leaving Egypt was only in one day, as it says explicitly by the commandment to remember going out of Egypt "In order that you remember the day you went out of Egypt {all the days of your life...}"?
