What does the Bible say about the breastplate of judgment?

The breastplate of judgment, as described in Exodus 28, was worn by Aaron, the high priest of Israel. This breastplate held twelve stones, each engraved with the names of the sons of Jacob, representing the tribes of Israel. Its significance lies in the fact that it symbolizes how Christ, our great high priest, carries His people, the elect, on His heart and shoulders. Just as the breastplate was placed over Aaron's heart, Christ bears His people in His presence, forever interceding for them before God.
