Commento su Levitico 3:3

‎'ואת כל החלב וגו [AND HE SHALL OFFER … ALL THE FAT THAT COVERETH THE INWARDS] AND ALL THE FAT [THAT IS UPON THE INWARDS] — These apparently redundant words are intended to include in the command the fat also that lies upon the maw. This is the opinion of Rabbi Ishmael; Rabbi Akiba holds that they are intended to include only the fat that is on the gut (Sifra, Vayikra Dibbura d'Nedavah, Section 14 6; cf. Chullin 49b).

The fat on the stomach. Meaning: The fat on the small intestines are included [as well] by kal vachomer, since they have two signs of forbidden [fats]: They are spread like a garment and they have a detachable membrane. Rabbi Akiva, though, says only the [fat on the] small intestines [are included] because they have two signs: They are spread like a garment and they have a detachable membrane, but [the fats] on the stomach are not spread like a garment, but rather are many pieces of fat [that are attached to the stomach]. The word תותב means a garment, as the Targum Onkeles [writes in Shemos 22:26] היא שמלתו = היא תותביה.

The fat. This is because it comes to atone for the sin committed due to having become fat, as it says (Devarim 32:15): And Yeshurun became fat and rebelled; you grew fat, thick and rotund. Therefore, he brings the fat as if he offered up his own fat.

'והקריב מזבח השלמים וגו , “he shall present from the peaceoffering, etc.,” nothing is mentioned here concerning the washing of the entrails and legs of peaceofferings, the reason being that these continue to belong to the owners of the respective animals, each one of whom will make his own arrangements concerning such procedures.

את החלב, “the fat;” the expression “fat,” is used to describe the best part of something. This is clear from the Targum, rendering the word as תרבא, i.e. a combination of abundance and excellence.
