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.
Leviticus
The fat of an improperly slaughtered animal and the fat of a fatally wounded animal may be used for any purpose, but you are surely not permitted to eat it.
Leviticus
An animal which has died on its own, or an animal that was fatally maimed, he must not eat to defile himself with it, I am Adonoy.
Exodus
You shall be men of holiness to Me, and you must not eat flesh that was torn off in the field. Throw it to the dog.
