“The children of Israel journeyed from Rameses to Sukkot, approximately six hundred thousand men on foot, beside children” (Exodus 12:37). “The children of Israel journeyed from Rameses.” Rabbi Shmuel says: Once they departed, they baked the dough that they kneaded, as it is stated: “They baked the dough” (Exodus 12:39). “It was at the end of four hundred and thirty years, it was on that very day that the entire host of the Lord departed from the land of Egypt” (Exodus 12:41).
“It was at the end of four hundred and thirty years” – from the moment that the decree was issued against them,26When God told Abraham his descendants would experience servitude and affliction in a foreign land; see Genesis 15:13. as they were in Egypt only two hundred and ten years. On the day that they descended to Egypt, on that very day [years later] they ascended [from Egypt], and on that very day Joseph had emerged from prison.
Therefore, that night is a celebration for all Israel, as it is stated: “It was a night of vigil for the Lord” (Exodus 12:42). In this world, He performed a miracle for them at night, as it was a transient miracle;27Israel would experience additional tragedies and suffering in the future. Thus, the redemption from Egypt was transient. however, in the future, the night will turn into day, as it is stated: “The light of the moon will be like the light of the sun, and the light of the sun will be sevenfold…” (Isaiah 30:26) – like the light that the Holy One blessed be He created initially, and He stored it in the Garden of Eden.
