הלכה אויף דברים 6:23

In every generation, one must show himself as if he personally had come out from the subjugation of Egypt; as it is stated (Deuteronomy 6:23), "And He took us out from there, etc." And regarding this, the Holy One, blessed be He, commanded in the Torah (Deut. 5:15, 15:15, 24:22), "Remember that you were a slave" - meaning to say, as if you yourself had been a slave, came out to freedom, and were redeemed.

And in each and every generation, a person is obligated to show himself as if he left Egypt, as it is stated (Exodus 13:8); "For the sake of this, did the Lord do [this] for me in my going out of Egypt." Not only our ancestors did the Holy One, blessed be He, redeem, but rather also us [together] with them did He redeem, as it is stated (Deuteronomy 6:23); "And He took us out from there, in order to bring us in, to give us the land which He swore unto our fathers."
