the tiara of a king ( Ezekiel 21:26 ; Isaiah 28:5 ; 62:3 ); the turban ( Job 29:14 ). In the New Testament a careful distinction is drawn between the diadem as a badge of royalty ( Revelation 12:3 ; 13:1 ; 19:12 ) and the crown as a mark of distinction in private life. It is not known what the ancient Jewish "diadem" was. It was the mark of Oriental sovereigns. (See CROWN .)
