Exodus 28:38 - Exposition

It shall be upon his forehead, that Aaron may bear the iniquity of the sacred things . Imperfection attaches to everything that man does; and even the sacrifices that the people offered to God required to be atoned for and purified. It was granted to the high priest in his official capacity to make the necessary atonement, and so render the people's gifts acceptable. For this purpose he was invested with an official holiness, proclaimed by the inscription upon the plate, which exhibited him as the type and representative of that perfectly Holy One, through whom alone can any real atonement be made to the Father. It shall be always upon his forehead — i.e; whenever he ministers.
