Mitre

(Heb. mitsnepheth), something rolled round the head; the turban
or head-dress of the high priest (Ex. 28:4, 37, 39; 29:6, etc.).
In the Authorized Version of Ezek. 21:26, this Hebrew word is
rendered "diadem," but in the Revised Version, "mitre." It was a
twisted band of fine linen, 8 yards in length, coiled into the
form of a cap, and worn on official occasions (Lev. 8:9; 16:4;
Zech. 3:5). On the front of it was a golden plate with the
inscription, "Holiness to the Lord." The mitsnepheth differed
from the mitre or head-dress (migba'ah) of the common priest.
