The Fat Upon the Innards and the Boundaries of Forbidden Fat

"The fat that covers the innards" (Leviticus 3:3): what does Scripture teach? Since it is said "all fat is the LORD's" (verse 16), "all fat and all blood you shall not eat," "for whoever eats fat shall be cut off" (Leviticus 7:25), one might think even the fat of the flanks is included; therefore it teaches "the fat that covers the innards." One might think it is not in the category of punishment but is in the category of prohibition; therefore it teaches "the fat that covers the innards." I would exclude the fat of consecrated animals but not exclude the fat of ordinary animals; therefore it teaches "the fat that covers the innards." One might think it is not in the category of punishment but is in the category of prohibition; therefore it teaches "the fat that covers the innards." I would exclude all of them but not exclude the fat of a fetus that covers its innards; therefore it teaches "fat and the two kidneys." One might think it is not in the category of punishment but is in the category of prohibition; therefore it teaches "fat and the two kidneys." One might think it is not in the category of prohibition but must still be offered; therefore it teaches "the fat of the two kidneys" (Leviticus 7:4). In the case of the guilt-offering, there is no need for Scripture to teach this, for it is a fortiori argument: if peace-offerings, not every kind of which requires the fat-tail, require the fat and the two kidneys, then the guilt-offering, every kind of which requires the fat-tail, surely should require the fat and the two kidneys. If so, why is "the fat of the two kidneys" stated regarding the guilt-offering? To learn from it, to tell you: just as the fat and the two kidneys stated regarding the guilt-offering exclude the fetus from the category, so the fat and the two kidneys stated here exclude the fetus from the category.
