A blue lace - The plate was fastened upon a blue band or fillet, so tied round the mitre as to show the plate in front.

The mitre - A twisted band of linen Exodus 28:39 coiled into a cap, to which the name mitre, in its original sense, closely answers, but which, in modern usage, would rather be called a turban.

And thou shalt put it on a blue lace,.... The plate of gold:

that it may be upon the mitre; either the plate or the lace; the lace is the nearest antecedent, but it seems by what follows it should be the plate:

upon the forefront of the mitre it shall be; the plate of gold; the mitre was of linen, a wrap of linen about the head, and was like a turban on it, in the top of it; it did not come down low upon the forehead, but left that bare for this plate of gold to be put upon it. Jarchi seems to understand all this of the lace, by comparing it with the following verse, and Exodus 39:31 as if the plate was represented as in the lace, and the lace upon the plate and upon the mitre above; all which he thinks is to be reconciled by observing, that the plate had three holes, and in every hole was a blue lace, and each lace was divided into two parts, so that there were six in all, two laces at each end of the plate, and two in the middle, by which they were fastened upon the top of the mitre, by which it was kept from falling off; and of this middle lace, he thinks, the text is to be understood. The Targum of Jonathan observes, that this plate was put on a blue lace, to make atonement for the impudent.

And thou shalt put it on a blue lace, that it may be upon the mitre; upon the forefront of the mitre it shall be.

37. mitre-crown-like cap for the head, not covering the entire head, but adhering closely to it, composed of fine linen. The Scripture has not described its form, but from Josephus we may gather that it was conical in shape, as he distinguishes the mitres of the common priests by saying that they were not conical-that it was encircled with swathes of blue embroidered, and that it was covered by one piece of fine linen to hide the seams.

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.
