Exodus 28:28-30

Amplified Bible, Classic Edition

²⁸ And they shall bind the breastplate by its rings to the rings of the ephod with a lace of blue, that it may be above the skillfully woven girding band of the ephod, and that the breastplate may not become loose from the ephod.

²⁹ So Aaron shall bear the names of the sons of Israel in the breastplate of judgment upon his heart when he goes into the Holy Place, to bring them in continual remembrance before the Lord.

³⁰ In the breastplate of judgment you shall put the Urim and the Thummim [unspecified articles used when the high priest asked God’s counsel for all Israel]; they shall be upon Aaron’s heart when he goes in before the Lord, and Aaron shall bear the judgment (rights, judicial decisions) of the Israelites upon his heart before the Lord continually.
