And Mosheh saw that the people were naked; for they had been stripped by the hand of Aharon of the holy crown which was upon their head, inscribed and beautified with the great and glorious Name; and that their evil report would go forth among the nations of the earth, and they would get to them an evil name unto their generations.

And Mosheh saw the people that they were uncovered; for they had been stripped of the golden crown which was upon their head, whereon the Name had been engraven and set forth, at Mount Horeb.
