הלכות גזילה ואבידה ה׳Robbery and Lost Property 5

Halacha 1א׳

אָסוּר לִקְנוֹת דָּבָר הַגָּזוּל מִן הַגַּזְלָן וְאָסוּר לְסַעֲדוֹ עַל שִׁנּוּיוֹ כְּדֵי שֶׁיִּקְנֵהוּ. שֶׁכָּל הָעוֹשֶׂה דְּבָרִים אֵלּוּ וְכַיּוֹצֵא בָּהֶן מְחַזֵּק יְדֵי עוֹבְרֵי עֲבֵרָה וְעוֹבֵר עַל (ויקרא יט יד) "וְלִפְנֵי עִוֵּר לֹא תִתֵּן מִכְשׁל":

It is forbidden to buy from a thief something stolen, and forbidden to dress it up with a modification so as to buy it. Anyone who does this, and other things like this, strengthens the hands of transgressors and [doing so] transgresses "do not put a stumbling block in front of the blind" (Lev. 19:14)

Halacha 2ב׳

אָסוּר לֵהָנוֹת בְּדָבָר הַגָּזוּל וַאֲפִלּוּ לְאַחַר יֵאוּשׁ. וְהוּא שֶׁיֵּדַע בְּוַדַּאי שֶׁדָּבָר זֶה הוּא הַגְּזֵלָה עַצְמָהּ. כֵּיצַד. יָדַע בְּוַדַּאי שֶׁבְּהֵמָה זוֹ גְּזוּלָה אָסוּר לִרְכֹּב עָלֶיהָ אוֹ לַחְרשׁ בָּהּ:

It is forbidden to have benefit from a robbed thing, even after the owner's despair — and this where he knows for a certainty that this thing is the robbed article itself. How so? If he knows for a certainty that this animal is robbed, it is forbidden to ride upon it or to plough with it.

Halacha 3ג׳

גָּזַל בַּיִת אוֹ שָׂדֶה אָסוּר לַעֲבֹר בְּתוֹכָהּ אוֹ לִכָּנֵס בָּהּ בַּחַמָּה מִפְּנֵי הַחַמָּה וּבַגְּשָׁמִים מִפְּנֵי הַגְּשָׁמִים. וְאִם דָּר בְּתוֹכָהּ חַיָּב לְהַעֲלוֹת שָׂכָר לַבְּעָלִים כְּדִין הַדָּר בַּחֲצַר חֲבֵרוֹ שֶׁלֹּא מִדַּעְתּוֹ. גָּזַל דְּקָלִים וְעָשָׂה מֵהֶן גֶּשֶׁר אָסוּר לַעֲבֹר עָלָיו. וְכֵן כָּל כַּיּוֹצֵא בָּזֶה:

If he robbed a house or a field, it is forbidden to pass through it, or to enter it in the sun because of the sun and in the rains because of the rains. And if he dwelt in it, he is obliged to credit rent to the owners, by the law of one who dwells in his fellow's courtyard without his knowledge. If he robbed palm trees and made a bridge of them, it is forbidden to pass over it. And so with all the like of this.
