We all have plenty to be thankful for, and in the time of the Beish HaMikdash and Mishkan, there were two forms of thanksgiving – the Korban Shelamim and the Korban Todah. The Shelamim was entirely voluntary, brought whenever someone felt the need to express gratitude for something. The Todah was offered when a person recovered from an illness, was released from jail, or crossed the ocean or desert.

The offeror would present the animal with 40 loaves of bread and crackers, and had to finish the entire feast within a day. No one should or could eat that amount in a day; you’d have to invite your friends and family to finish it before the evening. It then becomes a communal event where the offeror can celebrate publicly.

The 40 loaves of bread consisted of part chametz and part matza:

אִם עַל־תּוֹדָה יַקְרִיבֶנּוּ וְהִקְרִיב עַל־זֶבַח הַתּוֹדָה חַלּוֹת מַצּוֹת בְּלוּלֹת בַּשֶּׁמֶן וּרְקִיקֵי מַצּוֹת מְשֻׁחִים בַּשָּׁמֶן וְסֹלֶת מֻרְבֶּכֶת חַלֹּת בְּלוּלֹת בַּשָּׁמֶן׃ עַל־חַלֹּת לֶחֶם חָמֵץ יַקְרִיב קָרְבָּנוֹ עַל־זֶבַח תּוֹדַת שְׁלָמָיו׃ – If he offers it for thanksgiving, he shall offer together with the sacrifice of thanksgiving unleavened cakes with oil mixed in, unleavened wafers spread with oil, and cakes of choice flour with oil mixed in, well soaked. This offering, with cakes of leavened bread added, he shall offer along with his thanksgiving sacrifice of well-being. (7:12, 13)

The idea of matza is that it’s simple ingredients, simply prepared. When dough is allowed time to leaven, the naturally occurring yeast ferments sugars in the dough into carbon dioxide, puffing up the dough. Matza is dense, whereas chametz is quite literally full of air.

Mastery of the fermentation process in bread and wine is the quintessential hallmark that showcase human creativity and civilization, which is why chametz is typically associated with the ego.

Humans have a natural tendency to equate the quality of a decision with the quality of its outcome. In reality, we should be thinking about the probability distribution.

When you achieve or succeed at something, the world can look at you and be so impressed at the independence and skill it took. It’s natural to feel in control, self-sufficient, and like nothing can stop you. Whatever the obstacle was, it’s gone now, and what a great reason to throw a party!

To address precisely this hubris, R’ Shamshon Raphael Hirsch notes that the Torah requires us to temper public thanksgiving celebrations with the simplicity of matza.

There’s an element of randomness to outcome distributions. People don’t always get what they deserve in life, for better and for worse – what about other people in the same circumstances who had different results? We know it’s true: people who worked 80 hours a week and couldn’t pay the bills; and people who were lazy with no brains who made fortunes. People who were lovely yet never got married, and people who were ugly inside and out yet settled down just fine. People who didn’t look after themselves and never got sick a day in their life, and people who obsessed with fitness and got sick anyway.

It might feel like you put in the work, spent the time, and analyzed the matter exhaustively to stack the odds in your favor and set yourself up for a win – that’s what you’re supposed to do!

But even then, it might not be enough.

The secret sauce is that the outcome distribution has to go your way – the element of mazel, chance, or luck, also known as סיעתה דשמיא. Many business titans echo the same refrain – they’d trade all of their skill for just a little more luck.

The circumstances a person brings a Korban Toda aren’t all that miraculous; they’re pretty run of the mill. Perhaps thinking of the ordinary as extraordinary is a little wonky, but even taking the minimalist position, being thankful for things we expect to happen should frame where we truly stand. Just because we expect something to happen doesn’t mean it is going to. And when the outcome goes our way, Heaven has smiled, and we mustn’t take it for granted – we should be humble about it.

While the matza is made of the same stuff as the chametz, it’s not the same at all.

When we stand before God, we need to know that all we have are the simple ingredients. By publicly announcing his dependence on Hashem, a person earns back their independence.

Success should breed humility but is liberated by a simple thank you.
