were symbols of the sounding of this word, or the revelation and proclamation of the word. Through the robe, with this pendant attached, Aaron was represented as the recipient and medium of the word and testimony which came down from heaven; and this was the reason why he was not to appear before the Lord without that sound, lest he should forfeit his life. It was not because he would simply have appeared as a private person if he had gone without it, for he would always have the holy dress of a priest upon him, even when he was not clothed in the official decorations of the high priest; but because no mere priest was allowed to enter the immediate presence of the Lord.

This is all that can be determined with reference to its form. The diadem was the only thing about it that had any special significance. This was to be placed above (upon) Aaron's forehead, that he “might bear the iniquity of the holy things, which the children of Israel sanctified, with regard to all their holy gifts,...as an acceptableness for them before Jehovah.” עון נשׁא: to bear iniquity (sin) and take it away; in other words, to exterminate it by taking it upon one's self.
