Reference for Kelim 8:8
נִמְצָא מְקוֹם הַנָּחַת הָעֵצִים, רַבִּי יְהוּדָה אוֹמֵר, מִן הַשָּׂפָה הַחִיצוֹנָה וְלִפְנִים, טָמֵא. וַחֲכָמִים אוֹמְרִים, מִשָּׂפָה הַפְּנִימִית וְלַחוּץ, טָהוֹר. רַבִּי יוֹסֵי אוֹמֵר, מִכְּנֶגֶד שְׁפִיתַת הַקְּדֵרָה וְלִפְנִים, טָמֵא. מִכְּנֶגֶד שְׁפִיתַת הַקְּדֵרָה וְלַחוּץ, טָהוֹר. נִמְצָא מְקוֹם יְשִׁיבַת הַבַּלָּן, מְקוֹם יְשִׁיבַת הַצַּבָּע, מְקוֹם יְשִׁיבַת שֶׁל שׁוֹלְקֵי זֵיתִים, טָהוֹר. אֵין טָמֵא אֶלָּא מִן הַסְּתִימָה וְלִפְנִים:
If [a <em>sheretz</em>] was found in the [place in a stove] where wood is put - Rabbi Yehudah says: If it was within the outer edge, [the stove] becomes impure. But the Sages say: If it was outside the inner edge [the stove] remains pure. Rabbi Yose says: If it was found beneath the spot where the pot is placed and inwards, [the stove] becomes impure, but if it is beneath the spot where the pot is set and outwards, it remains pure. If it was found on the place where the bath-keeper sits, or where the dyer sits, or where the olive-boilers sit, [the stove] remains pure. It only becomes impure when [the <em>sheretz</em>] is found in the enclosed part and inwards.
