וְהִקְטִ֧יר הַכֹּהֵ֛ן אֶת־הַחֵ֖לֶב הַמִּזְבֵּ֑חָה וְהָיָה֙ הֶֽחָזֶ֔ה לְאַהֲרֹ֖ן וּלְבָנָֽיו׃
And the priest shall make the fat smoke upon the altar; but the breast shall be Aaron’s and his sons’.
Targum Jonathan on Leviticus
And the priest shall burn the fat upon the altar, and the breast shall be for Aharon and for his sons.
