Verse 38. Aaron must have this upon his forehead, that he may bear the iniquity of the holy things, and that they may be accepted before the Lord - Herein he was a type of Christ, the great Mediator between God and man. Thro' him what is amiss in our services is pardoned: even this would be our ruin, if God should enter into judgment with us: but Christ our high priest bears this iniquity; bears it for us, so as to bear it from us. Thro' him likewise what is good is accepted; our persons, our performances are pleasing to God upon the account of Christ's intercession, and not otherwise. His being holiness to the Lord, recommends all those to the divine favour that believe in him. Having such a high priest, we come boldly to the throne of grace.
Verse 39. The embroidered coat of fine linen - Was the innermost of the priestly garments, it reached to the feet, and the sleeves to the wrists, and was bound to the body with a girdle or sash of needlework. The mitre or diadem was of linen, such as kings anciently wore in the east, typifying the kingly office of Christ.
Verse 43. It shall be a statute for ever - That is, It is to continue as long as the priesthood continues. And it is to have its perpetuity in the substance, of which these things were the shadows.
