Diadem: 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.
