אֵלּוּ עוֹרוֹת טְמֵאִין מִדְרָס, עוֹר שֶׁחִשַּׁב עָלָיו לְשָׁטִיחַ, עוֹר סְקֹרְטְיָא, עוֹר קָטָבֹלְיָא, עוֹר הַחַמָּר, עוֹר הַכַּתָּן, עוֹר הַכַּתָּף, עוֹר הָרוֹפֵא, עוֹר הָעֲרִיסָה, עוֹר הַלֵּב שֶׁל קָטָן, עוֹר הַכַּר, עוֹר הַכֶּסֶת, מִדְרָס. עוֹר הַסָּרוֹק, עוֹר הַסּוֹרֵק, רַבִּי אֱלִיעֶזֶר אוֹמֵר, מִדְרָס. וַחֲכָמִים אוֹמְרִים, טְמֵא מֵת:
The following hides are susceptible to <i>midras</i> impurity: a hide which one intended to use as a rug, a hide used as an apron, a hide used as a bed-covering, a hide used by a donkey-driver, a hide used by a flax-worker, a hide used by a porter [who carries burdens on his shoulders], a hide used by a physician, a hide used for a cradle, a hide [used as a bib] for a child's chest, a hide for a cushion, a hide for a blanket; [all these are susceptible to] <i>midras</i> impurity. Regarding a hide used for [wrapping] combed wool, and a hide used by a wool-comber [to place upon his knees], Rabbi Eliezer says: [it is susceptible to] <i>midras</i> impurity; and the Sages say: [it is susceptible only to] corpse impurity.
