ויקרא 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).

And he shall offer of the sacrifice of the peace offering an offering made by fire to the Lord; the fat that covers the inwards, and all the fat that is upon the inwards,

וְהִקְרִיב֙ מִזֶּ֣בַח הַשְּׁלָמִ֔ים אִשֶּׁ֖ה לַיהֹוָ֑ה אֶת־הַחֵ֙לֶב֙ הַֽמְכַסֶּ֣ה אֶת־הַקֶּ֔רֶב וְאֵת֙ כׇּל־הַחֵ֔לֶב אֲשֶׁ֖ר עַל־הַקֶּֽרֶב׃
