וַיֵּ֧רֶד מֹשֶׁ֛ה מִן־הָהָ֖ר אֶל־הָעָ֑ם וַיְקַדֵּשׁ֙ אֶת־הָעָ֔ם וַֽיְכַבְּס֖וּ שִׂמְלֹתָֽם׃
Então Moisés desceu do monte ao povo, e santificou o povo; e lavaram os seus vestidos.
Targum Jonathan on Exodus
And Mosheh went down that day to the people, and prepared the people, and they blanched their clothes.
