וְהִבְדַּלְתֶּ֞ם בֵּֽין־הַבְּהֵמָ֤ה הַטְּהֹרָה֙ לַטְּמֵאָ֔ה וּבֵין־הָע֥וֹף הַטָּמֵ֖א לַטָּהֹ֑ר וְלֹֽא־תְשַׁקְּצ֨וּ אֶת־נַפְשֹֽׁתֵיכֶ֜ם בַּבְּהֵמָ֣ה וּבָע֗וֹף וּבְכֹל֙ אֲשֶׁ֣ר תִּרְמֹ֣שׂ הָֽאֲדָמָ֔ה אֲשֶׁר־הִבְדַּ֥לְתִּי לָכֶ֖ם לְטַמֵּֽא׃
E vós separareis entre os animais puros e os impuros, e entre as aves impuras e as puras, e não contamineis vossas almas com animais, aves ou tudo o que rasteja sobre a terra, que eu separei para vós como impuros.
Makkot
