"In every generation, one is obligated to regard himself as if he personally had gone out of Egypt, as it is written (Shmot 13:8), “And you shall tell your son on that day, saying, ‘It is because of this that Hashem did for me when I left Egypt’.” It is not only our fathers whom the Holy One redeemed [from slavery]; we, too, He redeemed with them, as it is written (Devarim 6:23), “He took us out of there in order to bring us, to give us the Land that He swore to our forefathers” (From the Pesach Haggadah).
