Halakhah sobre Êxodo 12:39

This matsa that we are eating, for the sake of what [is it]? For the sake [to commemorate] that our ancestors' dough did not have time to become leavened before the King of the kings of kings, the Holy One, blessed be He, revealed [Himself] to them and redeemed them, as it is stated (Exodus 12:39); "And they baked the dough which they brought out of Egypt into matsa cakes, since it did not rise; because they were expelled from Egypt, and could not tarry, neither had they made for themselves provisions."

It is from the roots of the commandment [that it is] so that we should always remember the miracles that were done for us in the exodus from Egypt, as is written with the lamb of the Pesach sacrifice (Sefer HaChinukh 5). And we should remember that which occurred to us with this matter - that as a result of the haste of the exodus, we baked the dough [into] matsah. As they could not wait until it rose, as it is written (Exodus 12:39), "And they baked the dough, etc."
