Lost Propertyאבידה

מָצָא סְפָרִים, קוֹרֵא בָהֶן אַחַת לִשְׁלֹשִׁים יוֹם. וְאִם אֵינוֹ יוֹדֵעַ לִקְרוֹת, גּוֹלְלָן. אֲבָל לֹא יִלְמֹד בָּהֶן בַּתְּחִלָּה, וְלֹא יִקְרָא אַחֵר עִמּוֹ. מָצָא כְסוּת, מְנַעֲרָהּ אַחַת לִשְׁלֹשִׁים יוֹם. וְשׁוֹטְחָהּ לְצָרְכָּהּ, אֲבָל לֹא לִכְבוֹדוֹ. כְּלֵי כֶסֶף וּכְלֵי נְחֹשֶׁת, מִשְׁתַּמֵּשׁ בָּהֶן לְצָרְכָּן, אֲבָל לֹא לְשָׁחֳקָן. כְּלֵי זָהָב וּכְלֵי זְכוּכִית, לֹא יִגַּע בָּהֶן עַד שֶׁיָּבֹא אֵלִיָּהוּ. מָצָא שַׂק אוֹ קֻפָּה, וְכָל דָּבָר שֶׁאֵין דַּרְכּוֹ לִטֹּל, הֲרֵי זֶה לֹא יִטֹּל:

If he found scrolls he must read them once every thirty days, and if he does not know how to read he should unroll them. But he may not learn from them something he has not yet learned, nor may another read with him. If he found clothing he must shake it out once every thirty days, and spread it out for [the clothing’s] own good, but not for his own honor. [If he found] silver or copper vessels he must use them for their own good but not so as to wear them out. [If he found] vessels of gold or glass he may not touch them until Elijah comes. If he found a sack or a large basket or anything that is not generally carried about, he may not carry it.

אַף הַשִּׂמְלָה הָיְתָה בִכְלָל כָּל אֵלֶּה. לָמָּה יָצָאת. לְהָקִּישׁ אֵלֶיהָ, לוֹמַר לְךָ, מַה שִּׂמְלָה מְיֻחֶדֶת שֶׁיֶּשׁ בָּהּ סִימָנִים וְיֶשׁ לָהּ תּוֹבְעִים, אַף כָּל דָּבָר שֶׁיֶּשׁ בּוֹ סִימָנִים וְיֶשׁ לוֹ תוֹבְעִים, חַיָּב לְהַכְרִיז:

A garment was also included amongst all these things (which one must proclaim, listed in Deut. 22:3). Why was it mentioned separately? To compare [other things] to it: to teach you just as a garment is distinct in that it has special marks and it has those who claim it, so too everything that has special marks and those who claim it must be proclaimed.
