Exodus 28:12 And thou shalt put the two stones upon the shoulders of the ephod for stones of memorial unto the children of Israel: and Aaron shall bear their names before the Lord upon his two shoulders for a memorial.
[Patriarchs & Prophets pp 351] 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.
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.
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.” 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.
Isaiah 52:11 Be ye clean, that bear the vessels of the Lord.
May The Lord add His blessing to the study of His word. God bless!
