28:31 The robe of the ephod - This was next under the ephod, and reached down to the knees, without sleeves, and was put on over their head, having holes on the sides to put the arms through, or, as Maimonides describes it, was not sewn together on the sides at all.

Aaron was hereby reminded that God is holy, and that his priests must be holy, devoted to the Lord. This must appear in their forehead, in open profession of their relation to God. It must be engraven like the engravings of a signet; deep and durable; not painted so as to be washed off, but firm and lasting; such must our holiness to the Lord be. Christ is our High Priest; through him sins are forgiven to us, and not laid to our charge. Our persons, our doings, are pleasing to God upon the account of Christ, and not otherwise.
