Gen 41:42
As an installation in this post of honour, the king handed him his signet-ring, the seal which the grand vizier or prime minister wore, to give authority to the royal edicts (Est 3:10), clothed him in a byssus dress (שׁשׁ, fine muslin or white cotton fabric), and put upon his neck the golden chain, which was usually worn in Egypt as a mark of distinction, as the Egyptian monuments show (Hgst. pp. 30, 31).
