וְהִקְרִ֨יב מִזֶּ֣בַח הַשְּׁלָמִים֮ אִשֶּׁ֣ה לַיהוָה֒ חֶלְבּוֹ֙ הָאַלְיָ֣ה תְמִימָ֔ה לְעֻמַּ֥ת הֶעָצֶ֖ה יְסִירֶ֑נָּה וְאֶת־הַחֵ֙לֶב֙ הַֽמְכַסֶּ֣ה אֶת־הַקֶּ֔רֶב וְאֵת֙ כָּל־הַחֵ֔לֶב אֲשֶׁ֖ר עַל־הַקֶּֽרֶב׃
And he shall present of the sacrifice of peace-offerings an offering made by fire unto the LORD: the fat thereof, the fat tail entire, which he shall take away hard by the rump-bone; and the fat that covereth the inwards, and all the fat that is upon the inwards,
Pirkei Avot
Rabbi Elazar said: Be diligent in the study of the Torah; And know how to answer an epicuros, And know before whom you toil, and that your employer is faithful, for He will pay you the reward of your labor.
