יָדָ֣יו תְּבִיאֶ֔ינָה אֵ֖ת אִשֵּׁ֣י יְהוָ֑ה אֶת־הַחֵ֤לֶב עַל־הֶֽחָזֶה֙ יְבִיאֶ֔נּוּ אֵ֣ת הֶחָזֶ֗ה לְהָנִ֥יף אֹת֛וֹ תְּנוּפָ֖ה לִפְנֵ֥י יְהוָֽה׃
His own hands shall bring the offerings of the LORD made by fire: the fat with the breast shall he bring, that the breast may be waved for a wave-offering before the LORD.
