Over the ephod was the breastplate, the most sacred of the priestly vestments. This was of the same material as the ephod. It was in the form of a square, measuring a span, and was suspended from the shoulders by a cord of blue from golden rings. The border was formed of a variety of precious stones, the same that form the twelve foundations of the City of God. Within the border were twelve stones set in gold, arranged in rows of four, and, like those in the shoulder pieces, engraved with the names of the tribes. The Lord’s direction was, “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.” Exodus 28:29. So Christ, the great High Priest, pleading His blood before the Father in the sinner’s behalf, bears upon His heart the name of every repentant, believing soul. Says the psalmist, “I am poor and needy; yet the Lord thinketh upon me.” Psalm 40:17. (PP 351.1) MC VC

At the right and left of the breastplate were two large stones of great brilliancy. These were known as the Urim and Thummim. By them the will of God was made known through the high priest. When questions were brought for decision before the Lord, a halo of light encircling the precious stone at the right was a token of the divine consent or approval, while a cloud shadowing the stone at the left was an evidence of denial or disapprobation. (PP 351.2) MC VC

The miter of the high priest consisted of the white linen turban, having attached to it by a lace of blue, a gold plate bearing the inscription, “Holiness to Jehovah.” Exodus 39:30. Everything connected with the apparel and deportment of the priests was to be such as to impress the beholder with a sense of the holiness of God, the sacredness of His worship, and the purity required of those who came into His presence. (PP 351.3) MC VC

Not only the sanctuary itself, but the ministration of the priests, was to “serve unto the example and shadow of heavenly things.” Hebrews 8:5. Thus it was of great importance; and the Lord, through Moses, gave the most definite and explicit instruction concerning every point of this typical service. The ministration of the sanctuary consisted of two divisions, a daily and a yearly service. The daily service was performed at the altar of burnt offering in the court of the tabernacle and in the holy place; while the yearly service was in the most holy. (PP 351.4) MC VC
