וְהֵנִיף֩ אוֹתָ֨ם הַכֹּהֵ֥ן ׀ תְּנוּפָה֮ לִפְנֵ֣י יְהוָה֒ קֹ֤דֶשׁ הוּא֙ לַכֹּהֵ֔ן עַ֚ל חֲזֵ֣ה הַתְּנוּפָ֔ה וְעַ֖ל שׁ֣וֹק הַתְּרוּמָ֑ה וְאַחַ֛ר יִשְׁתֶּ֥ה הַנָּזִ֖יר יָֽיִן׃
여호와 앞에 요제로 흔들 것이며 그것과 흔든 가슴과 든 넓적다리는 성물이라 다 제사장에게 돌릴 것이니라 그 후에는 나실인이 포도주를 마실 수 있느니라
Rashi on Numbers
קדש הוא לכהן IT IS HOLY FOR THE PRIEST — The cake, the wafer and the shoulder are a heave-offering for the priest.
Siftei Chakhamim
The loaf. The word הוא (it) which normally refers to a single item, refers to what was waved, as dictated by the context. Thus it refers to the three items and הוא is in place of הם (they).
Chizkuni
על חזה התנופה ועל שוק התרומה, “together with breast of waving and the thigh of heaving;” in other words: together with the breast and the thigh.
