Exodus 29:6

The holy crown. — The golden plate, inscribed with “Holiness to the Lord,” and attached to the mitre by a lace or riband, resembled the “diadems” worn in the East by monarchs, and regarded as the main emblem of their sovereignty. In Egypt, such a diadem is found first in the reign of Amenôphis IV. (Khuenaten), the ninth king of the eighteenth dynasty. The assignment of a crown to the high priest gave him that quasi-royal dignity which marked him as a type of our Lord in His threefold office of Prophet, Priest, and King.
