and a dead body's fat or mangled carcass's fat may be used for any {purpose}, but you certainly must not eat it.

"And [if there is] any person who eats a dead body or a mangled carcass, [whether] among the native or among the alien, then he shall wash his garments, and he shall wash [himself] with water, and he shall be unclean until the evening, and he shall be clean.

He shall not eat a [naturally] dead body or a mangled carcass, {so that he becomes unclean} by it; I [am] Yahweh.
