וְהוֹצִ֣יא אֶת־כָּל־הַ֠פָּר אֶל־מִח֨וּץ לַֽמַּחֲנֶ֜ה אֶל־מָק֤וֹם טָהוֹר֙ אֶל־שֶׁ֣פֶךְ הַדֶּ֔שֶׁן וְשָׂרַ֥ף אֹת֛וֹ עַל־עֵצִ֖ים בָּאֵ֑שׁ עַל־שֶׁ֥פֶךְ הַדֶּ֖שֶׁן יִשָּׂרֵֽף׃ (פ)
ele levará todo o novilho para fora do acampamento, a um lugar limpo onde se lança a cinza, e o queimará sobre lenha com fogo; onde se lança a cinza será queimado. {פ}
Mishnah Zevachim
As for the bullocks which were burnt and the goats which were burnt, their slaughtering is [done] at the north, and the reception of their blood is [done] at the north, and their blood requires sprinkling on the veil, and on the golden altar; [The omission of] a single one of these applications invalidates [the sacrifice]. He [the priest] pours the remainder of the blood on the western base of the altar; but if he did not pour it out, he did not invalidate [the sacrifice]. Both of these were burnt at the ash pit.
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.
