The Haggadah speaks of four questions, four cups of wine, four sons and four languages of redemption – “I will bring you out…, I will save you…, I will redeem you” and “I will take you…” (Shemos 6:6-7) – all alluding to our four exiles: Babylonia, Persia, Greece, and Rome. For these exiles all emanate from the exile of Egypt, just as their redemptions are rooted in the redemption from Egypt.
