Diadem
Easton's Bible Dictionary 1897
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.)

di'-a-dem: There are seven Bible references to the diadem, four in the Old Testament and three in the New Testament. The Hebrew words do not mark any clear distinctions.
(1) tsaniph, tsanoph, tsaniphah (all from tsanaph, primarily "to wrap," "dress," "roll") mean a headdress in the nature of a turban or piece of cloth wrapped or twisted about the head. The word is also rendered "hood," "mitre." Job 29:14: "My justice was as a robe and a diadem" (RVm, "turban"); Isa 62:3: "a royal diadem in the hand of thy God."
(2) tsephirah, means "a crown," "diadem," i.e. something round about the head; Isa 28:5 "a diadem of beauty, unto the residue of his people."
(3) mitsnepheth, means an official turban or tiara of priest or king, translated also "mitre." Eze 21:26: "Remove the mitre, and take off the crown."
(4) diadema, the Greek word in the New Testament for "diadem," means "something bound about the head." Found 3 t, all in Re 12:3: "a great red dragon .... and upon his heads seven diadems" (the King James Version "crowns"); Re 13:1: "a beast .... and on his horns ten diadems"; 19:11,12: "a white horse .... and upon his head are many diadems."
