וַיֵּ֧רֶד מֹשֶׁ֛ה מִן־הָהָ֖ר אֶל־הָעָ֑ם וַיְקַדֵּשׁ֙ אֶת־הָעָ֔ם וַֽיְכַבְּס֖וּ שִׂמְלֹתָֽם׃
Mosè discese dal monte al popolo, e fece ch’il popolo si santificasse, e si lavasse le vesti.
Targum Jonathan on Exodus
And Mosheh went down that day to the people, and prepared the people, and they blanched their clothes.
