In every generation, one must see himself as if he himself had personally come out of Egypt, as it is said: “You should say to your son on that day, ‘It is because of that which God did to me when I left Egypt.’ It is not only our ancestors that the Holy One Blessed Be He redeemed. Rather, he redeemed us too, along with them, as it is said: “He brought us out of there, in order so that he could bring us to and give us the land which He had promised to our ancestors.”
