See Exodus 28:12; the same names engraved on the stones of the breastplate were worn over the heart, the seat of the affections, as well as of the intellect, to symbolize the relation of love and of personal interest which the Lord requires to exist between the priest and the people.

And Aaron shall bear the names of the children of Israel in the breastplate of judgment upon his heart,.... Their names being engraven on the stones, and the stones put into the breastplate of judgment, and this breastplate hanging down upon the breast and heart of Aaron, he was a representative of the twelve tribes of Israel, as Christ his antitype is the representative of the whole Israel of God; and who lie near the heart of Christ, are set as a seal upon it, are engraven on the palms of his hands, and carried in his bosom, and whom he always presents to his divine Father, and are accepted in him: he represented them in eternity, and in time; in his sufferings and death, in his burial and resurrection from the dead, when they were crucified, buried, and raised with him; and he represents them now in heaven, where they sit together in heavenly places in him, as it here follows in the type:

when he goeth in unto the holy place; to trim the lamps and offer incense, and especially when he went into the most holy place once a year:

for a memorial before the Lord continually; for a memorial to himself, to pray for them when he appeared before the Lord, to put the Lord in remembrance of his covenant with them, and promises to them; see Gill on Exodus 28:12, Isaiah 43:26, the Targum of Jonathan is, "for a good memorial": not a memorial for evil, but for good.

In this way Aaron was to bear upon his breast the names of the sons of Israel engraved upon this breastplate, as a memorial before Jehovah, whenever he went into the sanctuary.

And Aaron shall bear the names of the children of Israel in the breastplate of judgment upon his heart, when he goeth in unto the holy place, for a memorial before the LORD continually.

(m) Aaron will not enter into the holy place in his own name, but in the name of all the children of Israel.

Margin heart

The place of affection. Cf. Ex 28:12.

28:15-30 The chief ornament of the high priest, was the breastplate, a rich piece of cloth, curiously worked. The name of each tribe was graven in a precious stone, fixed in the breastplate, to signify how precious, in God's sight, believers are, and how honourable. How small and poor soever the tribe was, it was as a precious stone in the breastplate of the high priest; thus are all the saints dear to Christ, however men esteem them. The high priest had the names of the tribes, both on his shoulders and on his breast, which reminds us of the power and the love with which our Lord Jesus pleads for those that are his. He not only bears them up in his arms with almighty strength, but he carries them in his bosom with tender affection. What comfort is this to us in all our addresses to God! The Urim and Thummim, by which the will of God was made known in doubtful cases, were put in this breastplate. Urim and Thummim signify light and integrity. There are many conjectures what these were; the most probable opinion seems to be, that they were the twelve precious stones in the high priest's breastplate. Now, Christ is our Oracle. By him God, in these last days, makes known himself and his mind to us, Heb 1:1,2; Joh 1:18. He is the true Light, the faithful Witness, the Truth itself, and from him we receive the Spirit of Truth, who leads into all truth.
