אֶלָא בְּשָׁעָה שֶׁיֵּשׁ מַצָּה וּמָרוֹר מֻנָּחִים לְפָנֶיך
When we say in the Hagadah “Because of this…” (בַּעֲבוּר זֶה) we are referring to the matza and the maror, as it says בְּשָׁעָה שֶׁיֵּשׁ מַצָּה וּמָרוֹר מֻנָּחִים לְפָנֶיךָ—referring to a time when these “props” are placed before you. The Sefas Emes points out that we have a mitzvah to remember the Exodus from Egypt every day of the year, yet there is a special obligation that can only be performed on Seder night, which is done with these props of matza and maror.
He also says that matza symbolizes the yetzer tov and leavened bread represents the yetzer hara. He questions that it seems odd that we should be allowed to eat bread for an entire year. If one should not eat it on Pesach because it is tantamount to being attached to the yetzer hara, why shouldn’t we abstain from it for the rest of the year, too? He answers that the Exodus from Egypt was when klal Yisrael was formed. This time period – the “infancy” of klal Yisrael – needed to be in a pure environment, totally free from the yetzer hara, so that the young nation would flourish. We use the props of pesach, matza and maror in order to clarify our mission in life.
So too the Jewish nation of today, after going through a week of living in this cleaner environment, and re-experiencing the Exodus from Egypt, grows to be strong enough to have a mitzvah of remembering the Exodus throughout the year. But after a week, we are now strong enough to remember the experience without the props – without “b’avor zeh” and therefore after Pesach we are able to eat bread.
What he is telling us is that we have a job on Pesach, which must sustain us throughout the year. Our job is to become infused with a clarity of thought and belief in Hashem through experiencing the Exodus from Egypt. The night of leil haseder is so potent, that it gives us the ability to start counting towards receiving the Torah.
May we merit that our personal Seder tables have a strong dose of “ze” – of this environment – which will enable us to re-experience the Exodus as we remember it twice a day until the next Seder.
