הֶחָשׁוּד לִמְכֹּר בְּכוֹר לְשֵׁם חֻלִּין, אֵין קוֹנִים מִמֶּנּוּ בְּשַׂר צְבָאִים, שֶׁדּוֹמֶה לִבְשַׂר עֲגָלִים. וְאֵין לוֹקְחִים מִמֶּנּוּ עוֹרוֹת שֶׁאֵינָם עֲבוּדִים, אֲפִלּוּ שֶׁל נְקֵבָה, שֶׁמָּא יַחְתֹּךְ זִכְרוּתוֹ וְיֹאמַר: שֶׁל נְקֵבָה הוּא. וְאֵין לוֹקְחִין מִמֶּנּוּ צֶמֶר, אֲפִלּוּ מְלֻבָּן. אֲבָל לוֹקְחִין מִמֶּנּוּ צֶמֶר טָווּי וּלְבָדִים וְעוֹרוֹת עֲבוּדִים.
One who is suspected of selling a firstborn as unconsecrated — one does not buy from him the flesh of gazelles, for it resembles the flesh of calves. And one does not buy from him hides that are untanned, even those of a female, lest he cut off its male organ and say: it is of a female. And one does not buy from him wool, even whitened. But one does buy from him spun wool, and felts, and tanned hides.
