וְרָחַ֨ץ אֶת־בְּשָׂר֤וֹ בַמַּ֙יִם֙ בְּמָק֣וֹם קָד֔וֹשׁ וְלָבַ֖שׁ אֶת־בְּגָדָ֑יו וְיָצָ֗א וְעָשָׂ֤ה אֶת־עֹֽלָתוֹ֙ וְאֶת־עֹלַ֣ת הָעָ֔ם וְכִפֶּ֥ר בַּעֲד֖וֹ וּבְעַ֥ד הָעָֽם׃
And he shall bathe his flesh in water in a holy place and put on his other vestments, and come forth, and offer his burnt-offering and the burnt-offering of the people, and make atonement for himself and for the people.
