Leviticus 7:24

He speaks still of the same kinds of beasts, and shews that this prohibition reaches not only to the fat of those beasts which were offered to God, but also of those that died, or were killed at home. And if this seems a superfluous prohibition, since the lean as well as the fat of such beasts were forbidden, Leviticus 22:8, it must be noted, that prohibition reached only to the priests, Leviticus 7:4.
