Exodus 28:36-38

36-38. A plate of pure gold This was the most notable feature of the mitre, or turban, and is, therefore, mentioned here before the blue lace and headdress, although in Exodus 39:28; Exodus 39:30-31, the mitre is first mentioned. This golden plate bore the inscription HOLINESS TO THE LORD, and, being attached by a blue lace so as to be upon the forefront of the mitre, it would appear as if set as a jewel upon Aaron’s forehead, and signifies that he, as high priest and atoning mediator in all matters of oblation and sacrifices, was set forth to bear the iniquity of the holy things. He, as the representative of a holy nation and consecrated people, sanctified unto God by remission of their sins and in the symbolism of all their holy gifts, was, while discharging the duties of his office, always to wear upon his forehead this symbol of the redemption and consecration of Israel. So intense was the conception of the holiness of Jehovah that even the holy things which the children of Israel consecrated were thought of as still containing some elements of iniquity, and this golden signet on Aaron’s forehead was a continual acknowledgment of this, and proclaimed the merciful provision by which the iniquity might be borne away and forgiven.
