31 "Make the robe that is worn with the ephod from a single piece of blue cloth, 32 with an opening for Aaron's head in the middle of it. Reinforce the opening with a woven collar so it will not tear. 33 Make pomegranates out of blue, purple, and scarlet yarn, and attach them to the hem of the robe, with gold bells between them. 34 The gold bells and pomegranates are to alternate all around the hem. 35 Aaron will wear this robe whenever he ministers before the Lord, and the bells will tinkle as he goes in and out of the Lord 's presence in the Holy Place. If he wears it, he will not die. 36 "Next make a medallion of pure gold, and engrave it like a seal with these words: HOLY TO THE Lord . 37 Attach the medallion with a blue cord to the front of Aaron's turban, where it must remain. 38 Aaron must wear it on his forehead so he may take on himself any guilt of the people of Israel when they consecrate their sacred offerings. He must always wear it on his forehead so the Lord will accept the people. 39 "Weave Aaron's patterned tunic from fine linen cloth. Fashion the turban from this linen as well. Also make a sash, and decorate it with colorful embroidery.

Matthew Henry's Commentary on Exodus 28:31-39

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.
