Diadem in Easton's Bible Dictionary
the tiara of a king (Ezek. 21:26; Isa. 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 (Rev. 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 -T0000929.)
