English: Do not read only “guard the matzos,” but “guard the mitzvos”: just as one does not let matzah become leavened, so one does not let a mitzvah become “leavened”; if a mitzvah comes to your hand, do it immediately.
Type of Learning
Al-tikri reading of matzos / mitzvos — prompt performance of mitzvos.
What Is Learned
A mitzvah that arrives should be done at once, without delay that “lets it ferment.”
