31 And thou shalt make the cloak of the ephod all of blue. 32 And its opening for the head shall be in the midst thereof; there shall be a binding of woven work at its opening round about; as the opening of a coat of mail, it shall be in it—it shall not rend. 33 And on the skirts thereof thou shalt make pomegranates of blue, and purple, and scarlet, round about the skirts thereof; and bells of gold between them round about: 34 a golden bell and a pomegranate, a golden bell and a pomegranate, in the skirts of the cloak round about. 35 And it shall be on Aaron for service; that his sound may be heard when he goeth into the sanctuary before Jehovah, and when he cometh out, that he may not die.

Commentary on Exodus 28:31-39
(Read Exodus 28:31-39)
The robe of the ephod was under the ephod, and reached down to the knees, without sleeves. Aaron must minister in the garments appointed. We must serve the Lord with holy fear, as those who know they deserve to die. A golden plate was fixed on Aaron's forehead, engraven with "Holiness to the Lord." 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.
