Leviticus 16:24

וְרָחַ֨ץ אֶת־בְּשָׂר֤וֹ בַמַּ֙יִם֙ בְּמָק֣וֹם קָד֔וֹשׁ וְלָבַ֖שׁ אֶת־בְּגָדָ֑יו וְיָצָ֗א וְעָשָׂ֤ה אֶת־עֹֽלָתוֹ֙ וְאֶת־עֹלַ֣ת הָעָ֔ם וְכִפֶּ֥ר בַּעֲד֖וֹ וּבְעַ֥ד הָעָֽם׃

καὶ λούσεται τὸ σῶμα αὐτοῦ ὕδατι ἐν τόπῳ ἁγίῳ καὶ ἐνδύαὐτοῦ, καὶ ἐξελθὼν ποιήσει τὸ ὁλοκάρπωμα αὐτοῦ καὶ τὸ ὁλοκάρπωμα τοῦ λαοῦ, καὶ ἐξιλάσεται περὶ αὑτοῦ καὶ περὶ τοῦ οἴκου αὐτοῦ καὶ περὶ τοῦ λαοῦ ὡς περὶ τῶν ἱερέων.

Lavará luego su carne con agua en el lugar del santuario, y después de ponerse sus vestidos saldrá, y hará su holocausto, y el holocausto del pueblo, y hará la reconciliación por sí y por el pueblo.

He is to bathe himself with water in a holy place and put on his own clothes. Then he must go out and sacrifice his burnt offering and the people ’s burnt offering to make atonement for himself and for the people.
