When a person entrusts keilim to an unlearned person or gives a k'li to an unlearned artisan to fix, they are considered to be impure because of the impurity associated with a human corpse and the impurity of midras. If the watchman is familiar with the owner of the keilim and knows that he is a priest who partakes of terumah, they are considered as pure with regard to the impurity associated with a corpse, but are considered to have contracted midras impurity. The rationale is that it is suspected that his wife sat on them while she was in the nidah state without his knowledge, since care is not taken with regard to ritual impurity in the homes of unlearned people.

הלכה ב

2.
When a person places his keilim down before an unlearned person and tells him: "Watch these for me," they are considered to have contracted midras impurity, but not the impurity associated with a human corpse. If he placed them on the shoulder of the unlearned person, they are considered to have contracted both types of impurity.
If one left his keilim in a synagogue, they are considered as pure, for it is not entirely a domain of unlearned persons. If he left his keilim in a bathhouse and found them as he left them, they are pure, but he is taught not to do this in the future.
If one left his vat or his cistern unattended, even if he entered a city and returned and found an unlearned person next to the vat or the cistern, they are considered as pure, because the unlearned person does not have license to enter.

הלכה ג
הַמּוֹסֵר מַפְתֵּחַ בֵּיתוֹ לְעַם הָאָרֶץ כָּל שֶׁבַּבַּיִת טָהוֹר שֶׁלֹּא מָסַר לוֹ אֶלָּא שְׁמִירַת הַמַּפְתֵּחַ:
כסף משנה
3.
When a person entrusts the key to his house to an unlearned person, everything in the house is considered as pure, for he entrusted only the key to him for safekeeping.

הלכה ד
הַמַּנִּיחַ כֵּלָיו בְּחַלּוֹנוֹת שֶׁל מֶרְחָץ וְנָעַל עֲלֵיהֶם אַף עַל פִּי שֶׁנָּתַן הַמַּפְתֵּחַ לְעַם הָאָרֶץ כֵּלָיו טְהוֹרִין. וְכֵן אִם חָתַם עַל הַחַלּוֹן אוֹ עָשָׂה לוֹ סִימָן אֲפִלּוּ מָצָא הַחוֹתָם מְקֻלְקָל הֲרֵי כָּל אֵלּוּ טְהוֹרִין:
כסף משנה
4.
When a person places his keilim in the lockers of a bathhouse and locked them, the keilim are pure, even if he gave the key to an unlearned person. Similarly, if he sealed the locker or made a sign on it, his keilim are pure even if the seal has been broken.

הלכה ה
הַמַּנִּיחַ עַם הָאָרֶץ בְּתוֹךְ בֵּיתוֹ לְשָׁמְרוֹ וְיָשַׁב הוּא מֵרָחוֹק בִּזְמַן שֶׁהוּא רוֹאֶה אֶת הַנִּכְנָסִין וְאֶת הַיּוֹצְאִין הֲרֵי כָּל שֶׁבַּבַּיִת מִן הָאֳכָלִין וְהַמַּשְׁקִין וּכְלִי חֶרֶס שֶׁאֵינוֹ מֻקָּף צָמִיד פָּתִיל טְמֵאִין אֲבָל הַמִּשְׁכָּבוֹת וְהַמֶּרְכָּבוֹת וּכְלִי חֶרֶס הַמֻּקָּף צָמִיד פָּתִיל טְהוֹרִין. וְאִם אֵינוֹ רוֹאֶה לֹא אֶת הַנִּכְנָסִין וְלֹא אֶת הַיּוֹצְאִין כָּל שֶׁבַּבַּיִת טָמֵא אֲפִלּוּ הָיָה כָּפוּת אוֹ כְּרוּת יָדַיִם וְרַגְלַיִם הַכּל טָמֵא מִפְּנֵי שֶׁהֵן בִּרְשׁוּת עַם הָאָרֶץ:

5.
When a chavair leaves an unlearned person in his house to watch it and the owner sits a certain distance away, when he sees the people who enter and depart, all the foods, liquids, and earthenware containers that are not tightly sealed are impure. By contrast, surfaces on which one lies or rides and earthenware containers that are tightly sealed are pure. If the owner cannot see the people who enter or depart, everything in the house is impure. Even if the unlearned person he left in the home was bound or had his hands and feet cut off, everything is considered as impure, because it was in the domain of an unlearned person.

הלכה ו

כסף משנה
6.
When a chavair slept in the home of an unlearned person and his clothes were folded and placed under his head and his sandal and his jug were placed before him, they are considered as pure, because they are assumed to be guarded by their owner. The unlearned person will not touch them for he will say to himself: "Now he will wake up and see me."

הלכה ז
עַם הָאָרֶץ שֶׁשָּׁאַל מֵחָבֵר מִטָּה שֶׁיָּשֵׁן עָלֶיהָ וְיָשַׁן עָלֶיהָ בְּתוֹךְ בֵּיתוֹ שֶׁל חָבֵר אֵין טָמֵא אֶלָּא אוֹתָהּ הַמִּטָּה וְעַד מָקוֹם שֶׁהוּא יָכוֹל לִפְשֹׁט אֶת יָדוֹ מֵאוֹתָהּ הַמִּטָּה וְלִגַּע:
כסף משנה
7.
When an unlearned person borrows a bed from a chavair and sleeps on it in the house of the chavair, only that bed and the area which he can touch when extending his hand from the bed are impure.

הלכה ח
חָבֵר שֶׁאָמַר לְעַם הָאָרֶץ שְׁמֹר לִי פָּרָה זוֹ שֶׁלֹּא תִּכָּנֵס לַבַּיִת אוֹ שֶׁלֹּא תְּשַׁבֵּר אֶת הַכֵּלִים הֲרֵי הַבַּיִת וְהַכֵּלִים טְהוֹרִים. שֶׁלֹּא מָסַר לוֹ אֶלָּא שְׁמִירַת הַפָּרָה. אֲבָל אִם אָמַר לוֹ שְׁמֹר לִי בַּיִת זֶה שֶׁלֹּא תִּכָּנֵס בּוֹ הַפָּרָה וְכֵלִים אֵלּוּ שֶׁלֹּא תְּשַׁבְּרֵם הֲרֵי הֵן טְמֵאִין:
כסף משנה
8.
When a chavair told an unlearned person: "Watch this cow for me so that it will not enter the house" or "...break these utensils," the house and the utensils are pure, for he charged him only with guarding the cow. If, however, he told him: "Watch this house for me so that the cow will not enter it" or "Watch these utensils so that it will not break them," the house and the utensils are impure.

הלכה ט
הַמַּנִּיחַ עַם הָאָרֶץ בְּתוֹךְ בֵּיתוֹ וְיָצָא הִנִּיחוֹ עֵר וּמְצָאוֹ עֵר יָשֵׁן וּמְצָאוֹ יָשֵׁן אוֹ שֶׁהִנִּיחוֹ עֵר וּמְצָאוֹ יָשֵׁן כָּל שֶׁבַּבַּיִת טָהוֹר. הִנִּיחוֹ יָשֵׁן וּמְצָאוֹ עֵר כָּל מָקוֹם הַקָּרוֹב מִמֶּנּוּ שֶׁהוּא יָכוֹל לִפְשֹׁט אֶת יָדוֹ וְלִגַּע בּוֹ טָמֵא. וְכֵן הַמַּנִּיחַ אֻמָּנִין בְּתוֹךְ בֵּיתוֹ אֵין טָמֵא אֶלָּא עַד מָקוֹם שֶׁיְּכוֹלִין לִפְשֹׁט אֶת יְדֵיהֶן וְלִגַּע. וְאֵין אוֹמְרִים שֶׁמָּא עָלוּ עַל גַּבֵּי כִּסֵּא אוֹ עַל סֻלָּם וְנָגְעוּ בַּכְּלִי אוֹ בָּאֳכָלִין הַתְּלוּיִין לְמַעְלָה בַּכֹּתֶל:

9.
The following rules apply when one leaves an unlearned person lying down in his house and departs. Whether he left him awake and discovered him awake when he returned, he left him sleeping and found him sleeping, or left him awake and found him sleeping, everything in the house is pure. If he left him asleep and he found him awake, any place that is close to him to which he can extend his hand and touch is impure.
Similarly, if one leaves craftsmen in his house, only the places that they can reach when they extend their hands and touch are impure. We do not say that perhaps they climbed onto a chair or a ladder and touched a k'li or food that was hanging on a high place on the wall.

הלכה י
אֵשֶׁת חָבֵר שֶׁהִנִּיחָה אֵשֶׁת עַם הָאָרֶץ טוֹחֶנֶת בְּתוֹךְ בֵּיתָה. אֲפִלּוּ פָּסְקָה הָרֵחַיִם וַאֲפִלּוּ הָיוּ שְׁתַּיִם אֵין טָמֵא אֶלָּא מָקוֹם שֶׁיְּכוֹלִין לִפְשֹׁט אֶת יָדָן וְלִגַּע. וְאֵין אוֹמְרִין שֶׁמָּא הָאַחַת טוֹחֶנֶת וְהַשְּׁנִיָּה בָּלְשָׁה כָּל שֶׁבַּבַּיִת וְשֶׁמָּא נִיתְלֵת וְעָלְתָה בַּמְּקוֹמוֹת הַגְּבוֹהוֹת:
כסף משנה
10.
When the wife of a chavair leaves the wife of an unlearned person - or two such women - to grind flour in her home, only the places which the wife of the unlearned person can reach when she extends her hand and touch are impure. This applies even if the mill stops for a time. We do not say that while one was grinding, the other searched through everything in the house and maybe even suspended herself and ascended to high places.

הלכה יא
הָאִשָּׁה שֶׁנִּכְנְסָה לְהוֹצִיא פַּת לֶעָנִי יָצָאת וּמְצָאַתּוּ עוֹמֵד בְּצַד כִּכָּרוֹת אֲפִלּוּ תְּרוּמָה הֲרֵי הֵן טְהוֹרוֹת שֶׁאֵין חֶזְקָתוֹ לִגַּע שֶׁלֹּא בִּרְשׁוּת. וְכֵן הָאִשָּׁה שֶׁיָּצְאָה וּמָצְאָה אֵשֶׁת עַם הָאָרֶץ חוֹתָה גֶּחָלִים מִתַּחַת הַקְּדֵרָה הֲרֵי הַקְּדֵרָה טְהוֹרָה:
כסף משנה
11.
When a woman standing at the entrance to her house went in to take out a loaf of bread for a poor man and when she came out, found him standing at the side of loaves of bread, they are pure - even if they are terumah. The rationale is that it can be assumed that he would not touch anything without permission. Similarly, if a woman departed and when she returned, found the wife of an unlearned person stirring the coals that are under her pot, the pot is pure.

הלכה יב

כסף משנה
12.
When tax-collectors for the ruling kingdom entered a house to take security for money that is owed, everything in the house is impure. If they are accompanied by a gentile, their word is accepted if they say they did not touch something, because they are possessed by fear of the gentile.
When does the above apply? When there are witnesses that they entered or they have security which they took in their hands. If, however, they say on their own initiative: "We entered, but did not touch anything," their word is accepted. The rationale is: the same person whose words aroused our suspicion also allayed it.

הלכה יג
הַגַּנָּבִים שֶׁנִּכְנְסוּ לְתוֹךְ הַבַּיִת אֵין טָמֵא אֶלָּא מְקוֹם רַגְלֵי הַגַּנָּבִים. מִפְּנֵי שֶׁהֵן מְפַחֲדִין מִלִּבְלֹשׁ אֶלָּא (דָּבָר) שֶׁנּוֹטְלִין בִּמְזֻמָּן. וּמַה הֵן מְטַמְּאִין בִּמְקוֹם הֲלִיכָתָן הָאֳכָלִין וְהַמַּשְׁקִין וּכְלֵי חֶרֶס הַפְּתוּחִים אֲבָל הַמִּשְׁכָּבוֹת וְהַמֶּרְכָּבוֹת וּכְלֵי חֶרֶס הַמֻּקָּפִין צָמִיד פָּתִיל טְהוֹרִין. וְאִם יֵשׁ עִמָּהֶן עַכּוּ''ם אוֹ אִשָּׁה הַכּל טָמֵא:
כסף משנה
13.
When thieves entered a house, only the path where the thieves walked is impure. The rationale is that they are afraid to search through the entire house. Instead, they take only what is at hand.
To what do they impart impurity on the path where they walk? To food, liquids, and open earthenware containers. Surfaces on which one lies or rides and earthenware containers that are sealed closed are pure. If there is a gentile or a woman among them, everything is impure.

הלכה יד
הַגַּבָּאִים וְהַגַּנָּבִים שֶׁעָשׂוּ תְּשׁוּבָה וְהֶחֱזִירוּ מֵעַצְמָן לֹא מֵחֲמַת יִרְאָה וְאָמְרוּ לֹא נָגַעְנוּ בְּכָל מַה שֶּׁהָיָה בַּבַּיִת כְּשֶׁנִּכְנַסְנוּ הֲרֵי אֵלּוּ נֶאֱמָנִים וַאֲפִלּוּ עַל מְקוֹם רַגְלֵיהֶן:
כסף משנה
14.
When tax-collectors and thieves repent and return the articles they took on their own initiative, and not because of fear, and when doing so, say: "When we entered, we did not touch anything that was in the house except what we took," their word is accepted even with regard to articles that were in their path.

הלכה טו
הַמַּנִּיחַ אֶת בֵּיתוֹ פָּתוּחַ וּמְצָאוֹ פָּתוּחַ אוֹ שֶׁמְּצָאוֹ נָעוּל. אֲפִלּוּ הִנִּיחוֹ נָעוּל וּמְצָאוֹ פָּתוּחַ וְלֹא נִגְנַב מִמֶּנּוּ כְּלוּם כָּל שֶׁבַּבַּיִת טָהוֹר. שֶׁאֲנִי אוֹמֵר הַגַּנָּבִים פְּתָחוּהוּ וְנִמְלְכוּ וְהָלְכוּ לָהֶם וְלֹא נִכְנְסוּ:
כסף משנה
15.
When a person leaves his house open and finds it open or finds it locked - and even if he left it locked and found it open - and nothing was stolen from it, everything in the house is pure. We assume that thieves opened the door and then changed their minds and did not enter.

הלכה טז
קוֹרְדוֹם שֶׁאָבַד בַּבַּיִת אוֹ שֶׁהִנִּיחוֹ בְּזָוִית זוֹ וּבָא וּמְצָאוֹ בְּזָוִית אַחֶרֶת הַבַּיִת טָמֵא שֶׁאֲנִי אוֹמֵר אָדָם טָמֵא נִכְנַס לְשָׁם וּנְטָלוֹ:
כסף משנה
16.
When a hatchet is lost in a house or left in one corner and found in another corner, all the contents of the house are impure, for we assume that an impure person entered the house and took it.

הלכה יז

כסף משנה
17.
When a person lives together with an unlearned person and shares a common courtyard, if he forgot articles in the courtyard - even barrels that were sealed close or an oven that was sealed close - they are considered as impure. For them to be considered as pure, he must construct a barrier ten handbreadths high around the oven so that it will not be in the domain of an unlearned person.

הלכה יח

כסף משנה
18.
When a chavair has a partition or a hut before the entrance to an unlearned person's home or an unlearned person has a partition or a hut before the entrance to a chavair's home, keilim in the hut or in the partition are impure, because the unlearned person has the right to enter this hut or this partition.

הלכה יט

כסף משנה
19.
When the roof of a chavair is above the roof of an unlearned person, thechavair may lay out utensils there and place pure foods there under the presumption that their status has not changed, even though the unlearned person could extend his hand and touch them. Similarly, if his neighbor is a gentile, he need not be concerned about impurity or wine used for libations to a false deity.
If the roofs were next to each other on the same level or the roof of the unlearned person was higher and the chavair laid out utensils or left pure foods on his roof, every place to which the unlearned person could extend his hand and touch is considered to be impure.

הלכה כ

כסף משנה
20.
When there are two courtyards, one inside the other, the inner one belonging to a chavair and the outer one, belonging to an unlearned person, the chavair may place his utensils in his courtyard and spread out his produce there, even though the unlearned person's hand could reach there. There is no suspicion that the unlearned person would touch them, because he would be considered as a thief.

הלכה כא

כסף משנה
21.
When a courtyard is divided by a lattice-work barrier, with a chavair's domain on one side and an unlearned person's domain on the other side, the pure food belonging to the chavair is considered as pure, even though the unlearned person's hand could reach there. There is no suspicion that the unlearned person would touch it, because it is in the domain of the chavair.

הלכה כב

כסף משנה
22.
When the bucket of a chavair fell into the well of an unlearned person and the chavair went to get materials to lift it up, it is considered as impure. The rationale is that it was left unattended in the domain of an unlearned person for a given time.

הלכה כג

23.
When the wife of an unlearned person enters the house of a chavair to take out the son or the daughter of the chavair or his animal, everything in the house is pure, because she entered without permission.
When a potter who is a chavair brings his pots to sell and he descends to a well to drink, those on the inner rows are pure, but those on the outer rows are impure. When does the above apply? When he placed them near the public domain, because the passersby will touch the outer ones as they walk by.
Different rules apply if they were placed down distant from the public domain. If he was carrying the tools of his trade in his hand, they are all impure, because his tools indicate that they were placed down to be sold and everyone will touch them. If he was not carrying the tools of his trade, they are all pure, for it can be assumed that no one touched them.
When a chavair places food or liquids down at the entrance to his store and enters, they are considered impure, for the passersby will touch them.
