וְהַשֹּׂרֵ֣ף אֹתָ֔ם יְכַבֵּ֣ס בְּגָדָ֔יו וְרָחַ֥ץ אֶת־בְּשָׂר֖וֹ בַּמָּ֑יִם וְאַחֲרֵי־כֵ֖ן יָב֥וֹא אֶל־הַֽמַּחֲנֶֽה׃
Orang yang membakar semuanya itu harus mencuci pakaiannya dan membasuh tubuhnya dengan air; sesudah itu barulah ia boleh masuk ke perkemahan.
Mishnah Yoma
He [the high priest] came to the bull and the goat that were to be burnt. He cut them open and took out the sacrificial portions and put them on a tray, and them burned them on the altar. He twisted them around carrying poles and took them out to the place of burning. And from when are his clothes unclean? After they have gone outside the walls of the Temple courtyard. Rabbi Shimon says: from the moment the fire has taken hold of most of them.
Mishnah Parah
The one who burns the red cow or bulls and he that leads away the scapegoat, defile garments. The red cow and the bulls and the scapegoat do not themselves defile garments. Behold [the garment] would say [to the person], "That which defiled you did not defile me, but you did defile me.
Mishnah Zevachim
Bullocks which are burned and goats which are burned: when they are burned in fulfillment of their prescribed commandment, they are burned in the ash depository (bet hadeshen), and they defile garments. But when they are not burned in fulfillment of their commandment, they are burned in the bet habirah and they do not defile garments.
