Alalahanin mo na naging alipin ka sa lupain ng Egipto; kaya iniuutos ko sa iyo na gawin ang bagay na ito.
Mishneh Torah, Leavened and Unleavened Bread
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.
