כָּל שָׁעָה שֶׁמֻּתָּר לֶאֱכֹל, מַאֲכִיל לַבְּהֵמָה לַחַיָּה וְלָעוֹפוֹת, וּמוֹכְרוֹ לַנָּכְרִי, וּמֻתָּר בַּהֲנָאָתוֹ. עָבַר זְמַנּוֹ, אָסוּר בַּהֲנָאָתוֹ, וְלֹא יַסִּיק בּוֹ תַּנּוּר וְכִירָיִם. רַבִּי יְהוּדָה אוֹמֵר, אֵין בִּעוּר חָמֵץ אֶלָּא שְׂרֵפָה. וַחֲכָמִים אוֹמְרִים, אַף מְפָרֵר וְזוֹרֶה לָרוּחַ אוֹ מַטִּיל לַיָּם:

The entire time that one is allowed to eat [chamets - leavened grain products], one may feed it to a domesticated animal, to a wild animal and to birds; or sell it to a gentile; and it is permitted to benefit from it. [After the] time [that it may still be eaten] has passed, it is prohibited to benefit from it, and one may not feed the fire of an oven or a pot range with it. 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."

חָמֵץ שֶׁל נָכְרִי שֶׁעָבַר עָלָיו הַפֶּסַח, מֻתָּר בַּהֲנָאָה. וְשֶׁל יִשְׂרָאֵל, אָסוּר בַּהֲנָאָה. שֶׁנֶּאֱמַר (שמות יג) לֹא יֵרָאֶה לְךָ שְׂאֹר:

If there exists chamets of a gentile, which [was in existence] during Pesach, it is permitted to benefit from it [after Pesach]; but [if it were] of an Israelite, it is forbidden to benefit from it [after Pesach], as it is stated (Exodus 13:7), "And there shall not be seen any leaven to you."

נָכְרִי שֶׁהִלְוָה אֶת יִשְׂרָאֵל עַל חֲמֵצוֹ, אַחַר הַפֶּסַח מֻתָּר בַּהֲנָאָה. וְיִשְׂרָאֵל שֶׁהִלְוָה אֶת הַנָּכְרִי עַל חֲמֵצוֹ, אַחַר הַפֶּסַח אָסוּר בַּהֲנָאָה. חָמֵץ שֶׁנָּפְלָה עָלָיו מַפֹּלֶת, הֲרֵי הוּא כִמְבֹעָר. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, כָּל שֶׁאֵין הַכֶּלֶב יָכוֹל לְחַפֵּשׂ אַחֲרָיו:

If a gentile lent money to an Israelite upon [the security] of [the latter's] chamets [and he defaults on the loan], it is permitted to benefit from it after Pesach; but when an Israelite has lent money to a gentile upon [the security] of [the latter's] chamets [and he defaults on the loan], it is forbidden to benefit from it after Pesach; If chamets has been covered by fallen ruins, behold it is as if it is destroyed; Rabban Shimon ben Gamliel says, "Only when [it is so covered that] a dog cannot search for it."

הָאוֹכֵל תְּרוּמַת חָמֵץ בְּפֶסַח בְּשׁוֹגֵג, מְשַׁלֵּם קֶרֶן וְחֹמֶשׁ. בְּמֵזִיד, פָּטוּר מִתַּשְׁלוּמִים וּמִדְּמֵי עֵצִים:

[A common Israelite] who eats terumah [a portion of a crop given to a Kohen which becomes holy upon separation, and can only be consumed by Kohanim or their household] that is chamets on Pesach, [if it be] through error, he must pay the principal, and the fifth part [in addition]; but if [he did it] willfully, he is exempt from payments, and [even of paying] for the value of the wood [if the chamets were to have been used for fuel in the place of wood].

אֵלּוּ דְבָרִים שֶׁאָדָם יוֹצֵא בָהֶן יְדֵי חוֹבָתוֹ בְּפֶסַח, בְּחִטִּים, בִּשְׂעוֹרִים, בְּכֻסְּמִין וּבְשִׁיפוֹן וּבְשִׁבֹּלֶת שׁוּעָל. וְיוֹצְאִין בִּדְמַאי וּבְמַעֲשֵׂר רִאשׁוֹן שֶׁנִּטְּלָה תְרוּמָתוֹ, וּבְמַעֲשֵׂר שֵׁנִי וְהֶקְדֵּשׁ שֶׁנִּפְדּוּ, וְהַכֹּהֲנִים בְּחַלָּה וּבִתְרוּמָה. אֲבָל לֹא בְטֶבֶל, וְלֹא בְמַעֲשֵׂר רִאשׁוֹן שֶׁלֹּא נִטְּלָה תְרוּמָתוֹ, וְלֹא בְמַעֲשֵׂר שֵׁנִי וְהֶקְדֵּשׁ שֶׁלֹּא נִפְדּוּ. חַלּוֹת תּוֹדָה וּרְקִיקֵי נָזִיר, עֲשָׂאָן לְעַצְמוֹ, אֵין יוֹצְאִין בָּהֶן. עֲשָׂאָן לִמְכֹּר בַּשּׁוּק, יוֹצְאִין בָּהֶן:

These are the [grains] with which a person may discharge his [obligation to eat matsa] on Pesach: with wheat, with barley, with spelt, and with rye, and with oats. We may discharge [our obligation] with demai‎ [produce from which it is uncertain whether tithes were already taken], and with ma'aser rishon [the first tithe of produce, which must be given to the Levi] from which terumah has been taken; and with ma'aser sheni [the second tithe of produce, which must be taken to Jerusalem and consumed there] and hekdesh [property, living or inanimate, devoted by its owner for sacred purposes, by which action he ceases to be its owner] which have been redeemed; and for Kohanim [members of the priestly caste, a subgroup of tribe of Levi, which is uniquely responsible for maintaining and carrying out the sacrificial services in the Temple] with challah [a portion of a batch of bread dough given to a Kohen which becomes holy upon separation, and can only be consumed by Kohanim or their household], and with terumah. But [we may] not [discharge our obligation] with tevel [produce from which the various tithes have not yet been separated]; and not with ma'aser rishon, from which terumah has not been taken; or with ma'aser sheni and hekdesh which have not been redeemed; and not with the loaves of a thank-offering, and the thin cakes of the offering of a nazir [a person who vows to avoid corpse impurity, refrain from cutting his hair and abstain from all grape products], if one had made them for his own use; if [however] he had made them to sell in the market, we may discharge [our obligation] with them.

אֵין שׁוֹרִין אֶת הַמֻּרְסָן לַתַּרְנְגוֹלִים, אֲבָל חוֹלְטִין. הָאִשָּׁה לֹא תִשְׁרֶה אֶת הַמֻּרְסָן שֶׁתּוֹלִיךְ בְּיָדָהּ לַמֶּרְחָץ, אֲבָל שָׁפָה הִיא בִּבְשָׂרָהּ יָבֵשׁ. לֹא יִלְעֹס אָדָם חִטִּין וְיַנִּיחַ עַל מַכָּתוֹ בְּפֶסַח, מִפְּנֵי שֶׁהֵן מַחֲמִיצוֹת:

We may not soak bran for chickens [on Pesach]; but we may scald it. A woman may not soak the bran which she takes with her to the bathhouse, but may rub it on her body [when it is] dry. One may not chew [grains of] wheat and place them [as a salve] on his wound, because they will become leavened.

אֵין נוֹתְנִין קֶמַח לְתוֹךְ הַחֲרֹסֶת אוֹ לְתוֹךְ הַחַרְדָּל, וְאִם נָתַן, יֹאכַל מִיָּד, וְרַבִּי מֵאִיר אוֹסֵר. אֵין מְבַשְּׁלִין אֶת הַפֶּסַח לֹא בְמַשְׁקִין וְלֹא בְמֵי פֵרוֹת, אֲבָל סָכִין וּמַטְבִּילִין אוֹתוֹ בָהֶן. מֵי תַשְׁמִישׁוֹ שֶׁל נַחְתּוֹם, יִשָּׁפְכוּ, מִפְּנֵי שֶׁהֵן מַחֲמִיצִין:

We may not put flour into charoset [a sweet mixture of fruits and spices eaten with the bitter herbs] or into mustard; if one did [so], he should eat [it] immediately. But Rabbi Meir forbids [it]. We may not boil the Pesach sacrifice, not with drinks and not with fruit juices; but [after it has been roasted] we may dab it or dip it in them. Water which a baker uses [in making the dough] must be thrown away [immediately], because it becomes leavened.
