Chapter 2

Chapter Two further develops the rules of Netilas Yadayim. The first Mishna clarifies the rules of how many time a person must rinse their hands. The second Mishna identifies limitations on the ability to purify מים ראשונים. The third Mishna elaborates on the previous Mishna and also identifies the area of the hand to which the decrees of Tumas Yadayim and Nettilas Yadayim apply. The last Mishna discusses cases where a doubt (Safek) has arisen regarding the purification status of the hands or the water.

Sources for Mishnah 2:1

The term Shtifah, rinsing, appears in our Mesechta and in the 11th Perek of Zevachim. See e.g., Zevachim 11:4.

(ד) אֶחָד הַבֶּגֶד וְאֶחָד הַשַּׂק וְאֶחָד הָעוֹר, טְעוּנִין כִּבּוּס בְּמָקוֹם קָדוֹשׁ. וּשְׁבִירַת כְּלִי חֶרֶס, בְּמָקוֹם קָדוֹשׁ. וּמְרִיקָה וּשְׁטִיפָה בִּכְלִי נְחשֶׁת, בְּמָקוֹם קָדוֹשׁ. זֶה חֹמֶר בַּחַטָּאת מִקָּדְשֵׁי קָדָשִׁים:

(4) Whether a garment, a sack, or a hide, it requires washing in a holy place. The breaking of an earthen vessel must be in a holy place. And the scouring and rinsing of a copper vessel must be in a holy place. In this the hatat is more stringent than [other] sacrifices of higher sanctity.

As is often the case, when setting out rules regarding Tumah and Tahara, the Mishnah will use a loaf of Terumah bread as the exemplar of a Tahor item that may be susceptible to the case of Tumah being discussed in the Mishnah. Many examples exist, including Terumot 8:11, Mikvaot 1:1and Zavim 5:5.

(יא) וְעַל זוֹ וְעַל זוֹ אָמַר רַבִּי יְהוֹשֻׁעַ, לֹא זוֹ הִיא תְרוּמָה שֶׁאֲנִי מֻזְהָר עָלֶיהָ מִלְּטַמְּאָהּ, אֶלָּא מִלְּאָכְלָהּ. וּבַל תְּטַמְּאָהּ כֵּיצַד, הָיָה עוֹבֵר מִמָּקוֹם לְמָקוֹם וְכִכָּרוֹת שֶׁל תְּרוּמָה בְיָדוֹ, אָמַר לוֹ נָכְרִי, תֶּן לִי אַחַת מֵהֶן וַאֲטַמְּאָהּ, וְאִם לָאו, הֲרֵי אֲנִי מְטַמֵּא אֶת כֻּלָּהּ, רַבִּי אֱלִיעֶזֶר אוֹמֵר, יְטַמֵּא אֶת כֻּלָּהּ, וְאַל יִתֶּן לוֹ אַחַת מֵהֶן וִיטַמֵּא. רַבִּי יְהוֹשֻׁעַ אוֹמֵר, יַנִּיחַ לְפָנָיו אַחַת מֵהֶן עַל הַסָּלַע:

(11) Concerning both cases Rabbi Joshua said: This is not the kind of terumah over which I am cautioned lest I defile it, but rather to eat of it and not to defile it. If one was passing from place to place with loaves of terumah in his hand and a Gentile said to him: “Give me one of these and I will make it unclean; for if not, I will defile them all,” let him defile them all, and not give him deliberately one to defile, the words of Rabbi Eliezer. But Rabbi Joshua says: he should place one of them on a rock.

(א) שֵׁשׁ מַעֲלוֹת בַּמִּקְוָאוֹת, זוֹ לְמַעְלָה מִזּוֹ, וְזוֹ לְמַעְלָה מִזּוֹ. מֵי גְבָאִים, שָׁתָה טָמֵא וְשָׁתָה טָהוֹר, טָמֵא. שָׁתָה טָמֵא וּמִלֵּא בִכְלִי טָהוֹר, טָמֵא. שָׁתָה טָמֵא וְנָפַל כִּכָּר שֶׁל תְּרוּמָה, אִם הֵדִיחַ, טָמֵא. וְאִם לֹא הֵדִיחַ, טָהוֹר:

(1) There are six degrees of mikvaot, each superior to the other. The water of pools [smaller than 40 seah] if an unclean person drank of it and then a clean person drank of it, he becomes unclean; If an unclean person drank of it and then drew water from it in a clean vessel, [the vessel] becomes unclean; If an unclean person drank of it and then a loaf of terumah fell in: If he washed [his hands] in it, it becomes unclean; But if he did not wash [his hands] in it, it continues clean.

(ה) הַטָּמֵא עַל מִקְצָת הַמִּשְׁכָּב וְהַטָּהוֹר עַל מִקְצָת הַמִּשְׁכָּב, טָמֵא. מִקְצָת טָמֵא עַל הַמִּשְׁכָּב וּמִקְצָת טָהוֹר עַל הַמִּשְׁכָּב, טָהוֹר. נִמְצֵאת טֻמְאָה נִכְנֶסֶת לוֹ וְיוֹצֵאת מִמֶּנּוּ בְּמִעוּטוֹ. וְכֵן כִּכָּר שֶׁל תְּרוּמָה שֶׁהוּא נָתוּן עַל גַּבֵּי מִשְׁכָּב וְהַנְּיָר בֵּינְתַיִם, בֵּין מִלְמַעְלָן בֵּין מִלְּמַטָּן, טָהוֹר. וְכֵן בְּאֶבֶן הַמְנֻגַּעַת, טָהוֹר. רַבִּי שִׁמְעוֹן מְטַמֵּא בָזוֹ:

(5) If an unclean person rests upon part of an object fit to lie upon, or a clean person rests upon part of an object fit to lie upon, it becomes unclean. If part of an unclean person rests on an object fit to lie upon, or part of a clean person rests upon an object fit to lie upon, it remains clean. Thus we find that impurity enters it and goes out of it by its lesser part. Similarly, if a loaf of terumah was placed upon an object fit to lie upon [that was unclean] and there paper in between, whether it was above or below, it remains clean. Similarly, in the case of a stone with scale disease it remains clean. Rabbi Shimon pronounced such a case unclean.

Sources for Mishnah 2:2

In discussing a Chatitzah on the hand, the Mishnah mentions a Keisom, a wood chip or splinter. We find word in both Beitza 4:6 and Chullin 9:4. This is not to be confused with Kisom, or ivy. We find reference to Kisom in Kilayim 5:8, Sukkah 1:4 and Ohalot 8:1.

(ו) רַבִּי אֱלִיעֶזֶר אוֹמֵר, נוֹטֵל אָדָם קֵיסָם מִשֶּׁלְּפָנָיו לַחֲצֹץ בּוֹ שִׁנָּיו. וּמְגַבֵּב מִן הֶחָצֵר וּמַדְלִיק, שֶׁכָּל מַה שֶּׁבֶּחָצֵר מוּכָן הוּא. וַחֲכָמִים אוֹמְרִים, מְגַבֵּב מִשֶּׁלְּפָנָיו וּמַדְלִיק:

(6) Rabbi Eliezer says: a man may take a chip from that which is lying before him to pick his teeth with it, and he may collect [chips] from the court yard and make a fire, for everything in a court is prepared [for use on Yom Tov]. But the sages say: he may collect only from that which is before him and make a fire.

(ד) עוֹר שֶׁיֵּשׁ עָלָיו כַּזַּיִת בָּשָׂר, הַנּוֹגֵע בְּצִיב הַיּוֹצֵא מִמֶּנּוּ, וּבְשַׂעֲרָה שֶׁכְּנֶגְדּוֹ, טָמֵא. הָיוּ עָלָיו כִּשְׁנֵי חֲצָאֵי זֵיתִים, מְטַמֵּא בְמַשָּׂא וְלֹא בְמַגָּע, דִּבְרֵי רַבִּי יִשְׁמָעֵאל. רַבִּי עֲקִיבָא אוֹמֵר, לֹא בְמַגָּע וְלֹא בְמַשָּׂא. וּמוֹדֶה רַבִּי עֲקִיבָא בִּשְׁנֵי חֲצָאֵי זֵיתִים שֶׁתְּחָבָן בְּקֵיסָם וֶהֱסִיטָן, שֶׁהוּא טָמֵא. וּמִפְּנֵי מָה רַבִּי עֲקִיבָא מְטַהֵר בָּעוֹר, מִפְּנֵי שֶׁהָעוֹר מְבַטְּלָן:

(4) A hide which had an olive’s bulk of [unclean] flesh clinging to it, one who touches a shred hanging from it, or a hair that was opposite to it, he becomes unclean. If there were two pieces of flesh attached to it, each the size of half an olive, they convey uncleanness by carrying but not by contact, the words of Rabbi Ishmael. Rabbi Akiva says: neither by contact nor by carrying. Rabbi Akiva agrees that if there were two pieces of flesh, each the size of half of an olive, that he stuck on a twig and he waved them, he becomes unclean. Why then does Rabbi Akiva declare him clean in the [case where they cling to the] hide? Because the hide renders them negligible.

(ח) הַמְקַיֵּם קוֹצִים בַּכֶּרֶם, רַבִּי אֱלִיעֶזֶר אוֹמֵר, קִדֵּשׁ. וַחֲכָמִים אוֹמְרִים, לֹא קִדֵּשׁ אֶלָּא דָבָר שֶׁכָּמוֹהוּ מְקַיְּמִין. הָאִירוּס וְהַקִּסּוֹם וְשׁוֹשַׁנַּת הַמֶּלֶךְ וְכָל מִינֵי זְרָעִים, אֵינָן כִּלְאַיִם בַּכָּרֶם. הַקַּנְבּוֹס, רַבִּי טַרְפוֹן אוֹמֵר, אֵינוֹ כִלְאָיִם, וַחֲכָמִים אוֹמְרִים, כִּלְאָיִם. וְהַקִּנְרָס, כִּלְאַיִם בַּכָּרֶם:

(8) One who allows thorns to remain growing in a vineyard: Rabbi Eliezer says: he [thereby] prohibits [the vineyard]. But the sages say: he does not prohibit except if it something that is generally allowed to grow. Iris, ivy, and the king’s lily, and all manner of seeds are not kilayim in a vineyard. [As for] hemp: Rabbi Tarfon said: it is not kilayim, But the sages say it is kilayim. Artichokes are kilayim in a vineyard.

(ד) הִדְלָה עָלֶיהָ אֶת הַגֶּפֶן וְאֶת הַדְּלַעַת וְאֶת הַקִּסּוֹם וְסִכֵּךְ עַל גַּבָּהּ, פְּסוּלָה. וְאִם הָיָה סִכּוּךְ הַרְבֵּה מֵהֶן, אוֹ שֶׁקְּצָצָן, כְּשֵׁרָה. זֶה הַכְּלָל, כֹּל שֶׁהוּא מְקַבֵּל טֻמְאָה וְאֵין גִּדּוּלוֹ מִן הָאָרֶץ, אֵין מְסַכְּכִין בּוֹ. וְכָל דָּבָר שֶׁאֵינוֹ מְקַבֵּל טֻמְאָה וְגִדּוּלוֹ מִן הָאָרֶץ, מְסַכְּכִין בּוֹ:

(4) If he trained a vine or a gourd or ivy over [the sukkah] and put skhakh on top of it, it is not valid. But if the skhakh is more than them, or if he cut them, it is valid. This is the general rule: whatever is susceptible to [ritual] impurity and does not grow from the ground may not be used for skhakh, but whatever is not susceptible to [ritual] impurity and does grow from ground soil may be used for skhakh.

(א) יֵשׁ מְבִיאִין אֶת הַטֻּמְאָה וְחוֹצְצִין, מְבִיאִין אֶת הַטֻּמְאָה וְלֹא חוֹצְצִין, חוֹצְצִין וְלֹא מְבִיאִין, לֹא מְבִיאִין וְלֹא חוֹצְצִין. אֵלּוּ מְבִיאִין וְחוֹצְצִין, הַשִּׁדָּה וְהַתֵּבָה וְהַמִּגְדָּל, כַּוֶּרֶת הַקַּשׁ, כַּוֶּרֶת הַקָּנִים, וּבוֹר סְפִינָה אֲלֶכְּסַנְדְּרִית, שֶׁיֶּשׁ לָהֶן שׁוּלַיִם וְהֵן מַחֲזִיקִים אַרְבָּעִים סְאָה בְלַח, שֶׁהֵם כּוֹרַיִם בְּיָבֵשׁ. וִירִיעָה, וּסְקוֹרְטְיָא, וּקְטָבֹלְיָא, וְסָדִין, וּמַפָּץ, וּמַחֲצֶלֶת, שֶׁהֵן עֲשׂוּיִין אֹהָלִים, וְעֵדֶר בְּהֵמָה טְמֵאָה וּטְהוֹרָה, וּמְכוֹנוֹת חַיָּה וָעוֹף, וְהָעוֹף שֶׁשָּׁכַן, וְהָעוֹשֶׂה מָקוֹם לְבֵנָה בַּשִּׁבֳּלִים, הָאֵירוּס וְהַקִּסּוֹם, וְיַרְקוֹת חֲמוֹר, וּדְלַעַת יְוָנִית, וְאֳכָלִים טְהוֹרִים. רַבִּי יוֹחָנָן בֶּן נוּרִי לֹא הָיָה מוֹדֶה בְּאֳכָלִים טְהוֹרִין, חוּץ מִן הָעִגּוּל שֶׁל דְּבֵלָה:

(1) Some things bring forth uncleanness and [also] a protect [against it]; [Some things] bring forth uncleanness but do not protect against it; [Some things] protect but do not bring forth; [Some things] do not bring forth nor do they protect. The following bring forth and protect against [impurity]: A chest, a box, a cupboard, a beehive of straw, a beehive of reeds, or the water-tank of an Alexandrian ship, such of which [objects] have [flat] bottoms and can contain [at least] forty seahs liquid measure or two kors dry measure. [Also] a curtain, a leather apron, a leather bedspread, a sheet, a matting underlay or a mat when made into tents. A herd of cattle, unclean or clean, packs of wild animals or birds, a resting bird, a [shady] place that [a woman] makes for her son among the ears of corn; The iris, the ivy, squitting cucumber, Greek gourds and clean foodstuffs. Rabbi Yohanan ben Nuri did not agree with regard to clean foodstuffs except in the case of a cake of dried figs.

Sources for Mishnah 2:3

In describing the nature of Netillas Yadayim, the Mishnah teaches that one need only be concerned regarding both Tumas Yadayim and Netillas Yadayim until the "Perek," the joint of the hands (this variably described as the middle knuckle of the fingers, the joint where the fingers meet the palm or the wrist). We find similar use in Peaschim 7:12 and Bechoros 7:6 and other places.

The term comes up frequently in Mishnayos and has many different, yet related, meanings. In Berochos 2:-2:2, it refers to the "Sections" of Birchas Kriyas Shema, while in Avos 6:3 it refers to a chapter of Torah. In Berochos 9:2, and Terumos 4:6 it means intervals (the Mishnah has many examples of this usage). Finally, in Tamid 7:3, it refers to a pause in the proceedings.

(יב) אֵבָר שֶׁיָּצָא מִקְצָתוֹ, חוֹתֵךְ עַד שֶׁמַּגִּיעַ לָעֶצֶם, וְקוֹלֵף עַד שֶׁמַּגִּיעַ לַפֶּרֶק, וְחוֹתֵךְ. וּבַמֻּקְדָּשִׁין קוֹצֵץ בַּקּוֹפִיץ, שֶׁאֵין בּוֹ מִשּׁוּם שְׁבִירַת הָעֶצֶם. מִן הָאֲגַף וְלִפְנִים כְּלִפְנִים, מִן הָאֲגַף וְלַחוּץ כְּלַחוּץ. הַחַלּוֹנוֹת וְעֹבִי הַחוֹמָה, כְּלִפְנִים:

(12) If part of a limb went outside, he cuts [the flesh] as far as the bone and pares it until he reaches the joint and cuts it away. But in the case of [other] sanctified meat he cuts it off with a large knife, because they are not subject to the [prohibition of] breaking a bone. From the door-stop and within it is as the inside; From the door-stop and without is as outside. The windows and the thickness of the wall are as the inside.

(ו) הַמַּקִּישׁ בְּקַרְסֻלָּיו, וּבְאַרְכּוּבוֹתָיו, וּבַעַל פִּיקָה, וְהָעִקֵּל. אֵיזֶהוּ עִקֵּל, כֹּל שֶׁמַּקִּיף פַּרְסוֹתָיו וְאֵין אַרְכּוּבוֹתָיו נוֹשְׁקוֹת זוֹ לָזוֹ. פִּיקָה יוֹצְאָה מִגּוּדָלוֹ, עֲקֵבוֹ יוֹצֵא לַאֲחוֹרָיו, פַּרְסָתוֹ רְחָבָה כְּשֶׁל אַוָּז. אֶצְבְּעוֹתָיו מֻרְכָּבוֹת זוֹ עַל זוֹ, אוֹ קְלוּטוֹת (לְמַעְלָה) עַד הַפֶּרֶק, כָּשֵׁר. לְמַטָּה מִן הַפֶּרֶק וַחֲתָכָהּ, כָּשֵׁר. הָיְתָה בוֹ יְתֶרֶת וַחֲתָכָהּ, אִם יֵשׁ בָּהּ עֶצֶם, פָּסוּל. וְאִם לָאו, כָּשֵׁר. יָתֵר בְּיָדָיו וּבְרַגְלָיו שֵׁשׁ וָשֵׁשׁ עֶשְׂרִים וְאַרְבַּע, רַבִּי יְהוּדָה מַכְשִׁיר, וַחֲכָמִים פּוֹסְלִים. הַשּׁוֹלֵט בִּשְׁתֵּי יָדָיו, רַבִּי פּוֹסֵל, וַחֲכָמִים מַכְשִׁירִים. הַכּוּשִׁי, וְהַגִּיחוֹר, וְהַלַּבְקָן, וְהַקִּפֵּחַ, וְהַנַּנָּס, וְהַחֵרֵשׁ, וְהַשּׁוֹטֶה, וְהַשִּׁכּוֹר, וּבַעֲלֵי נְגָעִים טְהוֹרִין, פְּסוּלִין בָּאָדָם, וּכְשֵׁרִין בַּבְּהֵמָה. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, שׁוֹטָה בַבְּהֵמָה אֵינָהּ מִן הַמֻּבְחָר, רַבִּי אֱלִיעֶזֶר אוֹמֵר, אַף בַּעֲלֵי דִלְדּוּלִין, פְּסוּלִין בָּאָדָם, וּכְשֵׁרִין בַּבְּהֵמָה:

(6) If one knocks his ankles [against each other, in walking] or rubs his legs [against each other]; a ba’al pikah and an ikkel. What is an ikkel? One whose knees do not touch each other when he puts his feet together. If he has a lump protruding from his thumb, or if his heel projects backward, or if his feet are wide like those of a goose. Or if his fingers lie one above the other. If they are webbed up to the joint, he is fit, if below the root, if he cuts it, he is also fit. If he has an additional finger and he cut it off, if there was a bone in it, he is unfit, but if not, he is fit. If he has additional fingers and additional toes, on each hand and foot six fingers and six toes, [making altogether] twenty-four [fingers and toes]: Rabbi Judah declares him fit, But the sages declare him unfit. One who has equal strength in both hands: Rabbi declares him unfit; But the sages declare him fit. A kushi, a gihur, a lavkan, a kippeah, a dwarf, a deaf-mute, an imbecile, one intoxicated, or afflicted with plague marks which are clean – [these defects] disqualify in human beings but not in animals. Rabban Shimon ben Gamaliel says: a mad animal is not a choice sacrifice. Rabbi Eliezer says: also those afflicted with dangling warts they are unfit in human beings but are fit in animals.

(א) הָיָה קוֹרֵא בַתּוֹרָה, וְהִגִּיעַ זְמַן הַמִּקְרָא, אִם כִּוֵּן לִבּוֹ, יָצָא. וְאִם לָאו, לֹא יָצָא. בַּפְּרָקִים שׁוֹאֵל מִפְּנֵי הַכָּבוֹד וּמֵשִׁיב, וּבָאֶמְצַע שׁוֹאֵל מִפְּנֵי הַיִּרְאָה וּמֵשִׁיב, דִּבְרֵי רַבִּי מֵאִיר. רַבִּי יְהוּדָה אוֹמֵר, בָּאֶמְצַע שׁוֹאֵל מִפְּנֵי הַיִּרְאָה, וּמֵשִׁיב מִפְּנֵי הַכָּבוֹד, בַּפְּרָקִים שׁוֹאֵל מִפְּנֵי הַכָּבוֹד, וּמֵשִׁיב שָׁלוֹם לְכָל אָדָם:

(ב) אֵלּוּ הֵן בֵּין הַפְּרָקִים, בֵּין בְּרָכָה רִאשׁוֹנָה לִשְׁנִיָּה, בֵּין שְׁנִיָּה לִשְׁמַע, וּבֵין שְׁמַע לִוְהָיָה אִם שָׁמֹעַ, בֵּין וְהָיָה אִם שָׁמֹעַ לְוַיֹּאמֶר, בֵּין וַיֹּאמֶר לֶאֱמֶת וְיַצִּיב. רַבִּי יְהוּדָה אוֹמֵר, בֵּין וַיֹּאמֶר לֶאֱמֶת וְיַצִּיב לֹא יַפְסִיק. אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן קָרְחָה, לָמָּה קָדְמָה שְׁמַע לִוְהָיָה אִם שָׁמֹעַ, אֶלָּא כְדֵי שֶׁיְּקַבֵּל עָלָיו עֹל מַלְכוּת שָׁמַיִם תְּחִלָּה, וְאַחַר כָּךְ יְקַבֵּל עָלָיו עֹל מִצְוֹת. וְהָיָה אִם שָׁמֹעַ לְוַיֹּאמֶר, שֶׁוְהָיָה אִם שָׁמֹעַ נוֹהֵג בַּיּוֹם וּבַלַּיְלָה, וַיֹּאמֶר אֵינוֹ נוֹהֵג אֶלָּא בַּיּוֹם:

(1) If one was reading in the Torah [the section of the Shema] and the time for its recital arrived, if he directed his heart [to fulfill the mitzvah] he has fulfilled his obligation, but if not he has not fulfilled his obligation. In the breaks [between sections] one may give greeting out of respect and return greeting; in the middle [of a section] one may give greeting out of fear and return it, the words of Rabbi Meir. Rabbi Judah says: in the middle one may give greeting out of fear and return it out of respect, in the breaks one may give greeting out of respect and return greeting to anyone.

(2) These are the breaks between the sections: between the first blessing and the second, between the second and “Shema,” between “Shema” and “And it shall come to pass if you listen” between “And it shall come to pass if you listen” and “And the Lord said” and between “And the Lord said” and “Emet veYatziv” (true and firm). Rabbi Judah says: between “And the Lord said” and “Emet veYatziv” one should not interrupt. Rabbi Joshua ben Korhah said: Why was the section of “Shema” placed before that of “And it shall come to pass if you listen”? So that one should first accept upon himself the yoke of the Kingdom of Heaven and then take upon himself the yoke of the commandments. Why does the section of “And it shall come to pass if you listen” come before that of “And the Lord said”? Because “And it shall come to pass if you listen” is customary during both day and night, whereas [the section] “And the Lord said” is customary only during the day.

(ג) הַלּוֹמֵד מֵחֲבֵרוֹ פֶּרֶק אֶחָד אוֹ הֲלָכָה אַחַת אוֹ פָסוּק אֶחָד אוֹ דִבּוּר אֶחָד אוֹ אֲפִלּוּ אוֹת אַחַת, צָרִיךְ לִנְהוֹג בּוֹ כָבוֹד, שֶׁכֵּן מָצִינוּ בְדָוִד מֶלֶךְ יִשְׂרָאֵל, שֶׁלֹּא לָמַד מֵאֲחִיתֹפֶל אֶלָּא שְׁנֵי דְבָרִים בִּלְבָד, קְרָאוֹ רַבּוֹ אַלּוּפוֹ וּמְיֻדָּעוֹ, שֶׁנֶּאֱמַר (תהלים נה) וְאַתָּה אֱנוֹשׁ כְּעֶרְכִּי אַלּוּפִי וּמְיֻדָּעִי. וַהֲלֹא דְבָרִים קַל וָחֹמֶר, וּמַה דָּוִד מֶלֶךְ יִשְׂרָאֵל, שֶׁלֹּא לָמַד מֵאֲחִיתֹפֶל אֶלָּא שְׁנֵי דְבָרִים בִּלְבַד קְרָאוֹ רַבּוֹ אַלּוּפוֹ וּמְיֻדָּעוֹ, הַלּוֹמֵד מֵחֲבֵרוֹ פֶּרֶק אֶחָד אוֹ הֲלָכָה אַחַת אוֹ פָסוּק אֶחָד אוֹ דִבּוּר אֶחָד אוֹ אֲפִלּוּ אוֹת אַחַת, עַל אַחַת כַּמָּה וְכַמָּה שֶׁצָּרִיךְ לִנְהוֹג בּוֹ כָבוֹד. וְאֵין כָּבוֹד אֶלָּא תוֹרָה, שֶׁנֶּאֱמַר (משלי ג) כָּבוֹד חֲכָמִים יִנְחָלוּ, (משלי כח) וּתְמִימִים יִנְחֲלוּ טוֹב, וְאֵין טוֹב אֶלָּא תוֹרָה, שֶׁנֶּאֱמַר (משלי ד) כִּי לֶקַח טוֹב נָתַתִּי לָכֶם תּוֹרָתִי אַל תַּעֲזֹבוּ:

(3) One who learns from his fellow one chapter, or one halakhah, or one verse, or one word, or even one letter, is obligated to treat him with honor; for so we find with David, king of Israel, who learned from Ahitophel no more than two things, yet called him his master, his guide and his beloved friend, as it is said, “But it was you, a man mine equal, my guide and my beloved friend” (Psalms 55:14). Is this not [an instance of the argument] “from the less to the greater” (kal vehomer)? If David, king of Israel who learned from Ahitophel no more than two things, nevertheless called him his master, his guide and his beloved friend; then in the case of one who learns from his fellow one chapter, or one halakhah, or one verse, or one word, or even one letter, all the more so he is under obligation to treat him with honor. And “honor’” means nothing but Torah, as it is said, “It is honor that sages inherit” (Proverbs 3:35). “And the perfect shall inherit good” (Proverbs 28:10), and “good” means nothing but Torah, as it is said, “For I give you good instruction; do not forsake my Torah” (Proverbs 4:2).

(ב) עַל הַזִּיקִין, וְעַל הַזְּוָעוֹת, וְעַל הַבְּרָקִים, וְעַל הָרְעָמִים, וְעַל הָרוּחוֹת, אוֹמֵר בָּרוּךְ שֶׁכֹּחוֹ וּגְבוּרָתוֹ מָלֵא עוֹלָם. עַל הֶהָרִים, וְעַל הַגְּבָעוֹת, וְעַל הַיַּמִּים, וְעַל הַנְּהָרוֹת, וְעַל הַמִּדְבָּרוֹת, אוֹמֵר בָּרוּךְ עוֹשֵׂה מַעֲשֵׂה בְרֵאשִׁית. רַבִּי יְהוּדָה אוֹמֵר, הָרוֹאֶה אֶת הַיָּם הַגָּדוֹל אוֹמֵר בָּרוּךְ שֶׁעָשָׂה אֶת הַיָּם הַגָּדוֹל, בִּזְמַן שֶׁרוֹאֶה אוֹתוֹ לִפְרָקִים. עַל הַגְּשָׁמִים וְעַל הַבְּשׂוֹרוֹת הַטּוֹבוֹת אוֹמֵר בָּרוּךְ הַטּוֹב וְהַמֵּטִיב, וְעַל שְׁמוּעוֹת רָעוֹת אוֹמֵר בָּרוּךְ דַּיַּן הָאֱמֶת:

(2) [On witnessing] comets, earthquakes, thunder, or windy storms one says, “Blessed be He whose strength and might fill the world.” [On seeing] mountains, hills, seas, rivers or deserts one says, “Blessed be He who made creation.” Rabbi Judah says: one who sees the Great Sea should say, “Blessed be He who made the Great Sea,” if he sees it at intervals. For rain and for good news one says, “Blessed be He that is good and grants good.” For bad news one says, “Blessed be the true judge.”

(ו) בִּשְׁלֹשָׁה פְרָקִים מְשַׁעֲרִים אֶת הַכַּלְכָּלָה, בַּבַּכּוּרוֹת, וּבַסְּיָפוֹת, וּבְאֶמְצַע הַקָּיִץ. הַמּוֹנֶה, מְשֻׁבָּח. וְהַמּוֹדֵד, מְשֻׁבָּח מִמֶּנּוּ. וְהַשּׁוֹקֵל, מְשֻׁבָּח מִשְּׁלָשְׁתָּן:

(6) On three occasions they measure the contents of the basket: At the full time of the first ripe fruits, and of the late summer fruits, and in the middle of the summer. He who counts [the fruit] is praiseworthy, he who measures it is more praiseworthy, and he who weighs them is most praiseworthy of all.

(3) If the high priest wished to burn the offerings [himself], he would go up the ascent with the deputy high priest at his right. When he reached the middle of the ascent the deputy took hold of his right hand and helped him up. The first [of the other priests] then handed to him the head and the foot and he laid his hands on them and threw them [onto the altar]. The second then handed to the first the two fore legs. And he handed them to the high priest who laid his hands on them and threw them [onto the altar]. The second then went away. In the same way all the other limbs were handed to him and he laid his hands on them and threw them [on to the altar fire]. If he wanted, he could lay his hands and let others throw [them] on the fire. He then went around the altar. From where did he begin? From the southeastern corner; from there he went to the northeastern, then to the northwestern and then to the southwestern. They there handed him the wine for libation. The deputy high priest stood on the corner/horn of the altar with the flags in his hand, and two priests on the table of the fats with two trumpets in their hands. They blew a teki’ah, a teru’ah and a teki’ah. They then went and stood by Ben Arza, one on his right hand and one on his left. When he bent down to make the libation the deputy high priest waved the flags and Ben Arza struck the cymbals and the Levites sang the psalm. When they came to a pause they blew a teki’ah, and the public bowed down. At every pause there was a teki’ah and at every teki’ah a bowing down. This was the order of the regular daily sacrifice for the service of our Lord. May it be His will that it be rebuilt speedily in our days, Amen.

Sources for Mishnah 2:4

The second half of the Mishna describes a number of situations in which a person in uncertain whether his hands contracted Tumah (ליטמא) or his Tamei hands transmitted Tumah to another object (ולטמא). The core concept of our Mishnah, that we are lenient when it comes to cases of doubt related to Netillas and Tumas Yadayim can be found in Mesechtas Taharos 4:7 and 4:11 (each case without the exception of R' Yose).

But if a condition of doubt arose concerning a father of uncleanness even though it was only rabbinical, it is deemed unclean.
