וְכָל־נֶ֗פֶשׁ אֲשֶׁ֨ר תֹּאכַ֤ל נְבֵלָה֙ וּטְרֵפָ֔ה בָּאֶזְרָ֖ח וּבַגֵּ֑ר וְכִבֶּ֨ס בְּגָדָ֜יו וְרָחַ֥ץ בַּמַּ֛יִם וְטָמֵ֥א עַד־הָעֶ֖רֶב וְטָהֵֽר׃
And every soul that eateth that which dieth of itself, or that which is torn of beasts, whether he be home-born or a stranger, he shall wash his clothes, and bathe himself in water, and be unclean until the even; then shall he be clean.
