Exodus 28:29-31

Amplified Bible

²⁹ So Aaron shall carry the names of the sons of Israel (Jacob) in the breastpiece of judgment over his heart when he enters the Holy Place, to bring them in continual remembrance before the Lord. ³⁰ In the breastpiece of judgment you shall put the ^[a]Urim (Lights) and the Thummim (Perfections) [to be used for determining God’s will in a matter]. They shall be over Aaron’s heart whenever he goes before the Lord, and Aaron shall always carry the judgment (verdict, judicial decisions) of the sons of Israel over his heart before the Lord.

³¹ “And you shall make the ^[b]robe of the ephod all of blue.
