(15) Seven days you shall eat unleavened bread; on the very first day you shall remove leaven from your houses, for whoever eats leavened bread from the first day to the seventh day, that person shall be cut off from Israel. ...(19) No leaven shall be found in your houses for seven days. For whoever eats what is leavened, that person shall be cut off from the community of Israel, whether he is a stranger or a citizen of the country. (20) You shall eat nothing leavened; in all your settlements you shall eat unleavened bread.
(7) Throughout the seven days unleavened bread shall be eaten; no leavened bread shall be found with you, and no leaven shall be found in all your territory. (8) And you shall explain to your son on that day, ‘It is because of what the LORD did for me when I went free from Egypt.’

(ב) אֵין חוֹשְׁשִׁין שֶׁמָּא גָרְרָה חֻלְדָּה מִבַּיִת לְבַיִת וּמִמָּקוֹם לְמָקוֹם, דְּאִם כֵּן, מֵחָצֵר לְחָצֵר וּמֵעִיר לְעִיר, אֵין לַדָּבָר סוֹף:
(1) On the evening of the fourteenth [of Nissan] we check for chamets [leavened grain products] by candlelight. Any place into which we do not bring chamets does not require checking. And why did [the Sages] say [that we must check up to] two rows in the wine cellar? [It is] a place which we bring leavened bread into. Beit Shammai says, "Two rows upon the entire wine-cellar." But Beit Hillel says, "The two outer rows, which are the uppermost."
(2) We do not need to be concerned [that] perhaps a weasel [chulda] dragged [chamets] from [one] house to [another] house, or from [one] place to [another] place. Since if [we were to be concerned, we would also need to be concerned that chamets was dragged] from [one] courtyard to [another] courtyard, and from [one] city to [another] city — there [would be] no end to the matter.
אמר אביי לא קשיא הא בארבעה עשר הא בשלשה עשר בשלשה עשר דשכיח ריפתא בכולהו בתי לא מצנעא בארבעה עשר דלא שכיחא ריפתא בכולהו בתי מצנעא אמר רבא וכי חולדה נביאה היא דידעא דהאידנא ארביסר ולא אפי עד לאורתא ומשיירא ומטמרא אלא אמר רבא מה שמשייר יניחנו בצנעה שמא תטול חולדה בפנינו ויהא צריך בדיקה אחריו
Abaye said: This is not difficult; this ruling is referring to the fourteenth of Nisan, whereas that ruling is referring to the thirteenth. The Gemara elaborates: On the thirteenth of Nisan, when bread is still found in every house, the weasel does not conceal the leaven, and therefore there is no concern that perhaps the weasel dragged the leaven elsewhere and concealed it. However, on the fourteenth of Nisan, when bread is not found in any of the houses, the weasel hides the leaven. Rava said in surprise: And is the weasel a prophetess that knows that now is the fourteenth of Nisan and no one will bake until the evening, and it leaves over bread and conceals it in its hole?

(14) So the priest Hilkiah, and Ahikam, Achbor, Shaphan, and Asaiah went to the prophetess Huldah—the wife of Shallum son of Tikvah son of Harhas, the keeper of the wardrobe—who was living in Jerusalem in the Mishneh, and they spoke to her. (15) She responded: “Thus said the LORD, the God of Israel: Say to the man who sent you to me: (16) Thus said the LORD: I am going to bring disaster upon this place and its inhabitants, in accordance with all the words of the scroll which the king of Judah has read.
רַבִּי יְהוּדָה אוֹמֵר, אֵין בִּעוּר חָמֵץ אֶלָּא שְׂרֵפָה. וַחֲכָמִים אוֹמְרִים, אַף מְפָרֵר וְזוֹרֶה לָרוּחַ אוֹ מַטִּיל לַיָּם:
Rabbi Yehuda says, "The destruction of chamets may not be done except by burning. But the Sages say, "One may also crumble [it] and throw [it] into the wind or put [it] in the sea."

Chametz is any grain product touched by yeast. It is likely ancient Israelites abstained from yeast in this season as an encouragement to the new grain, that it not become too wet and ferment on the stalk. However, in Jewish tradition, chametz came to represent arrogance, pride, and puffedupness. In the Talmud (Berachot 17a), Rabbi Alexandri says the following prayer: “Ribon ha’olamim, galu veyadua lefanecha sheretzoneinu laasot retzoncha, master of the worlds, it is known before You that our will is to perform your will. Umi me’akev? Se’or sheba’isah. What prevents us from doing your will? The yeast in the dough.” In other words, our selfish impulses are kneaded all through us like yeast in dough, and it’s hard to separate them out. So Passover became a time to remove internal chametz as well as external chametz. The Chasidic thinker known as the Sefat Emet understands chametz as arrogance and matzah as humility, and points out that lechachmitz means to miss an opportunity. To remove the chametz, the arrogance, is to discover more opportunities to connect and grow.
