Exodus 28:29-31

New Century Version

²⁹ “When Aaron enters the Holy Place, he will wear the names of the sons of Israel over his heart, on the chest covering that helps in making decisions. This will be a continual reminder before the Lord. ³⁰ And put the Urim and Thummim inside the chest covering so that they will be on Aaron’s heart when he goes before the Lord. They will help in making decisions for the Israelites. So Aaron will always carry them with him when he is before the Lord.

³¹ “Make the outer robe to be worn under the holy vest, using only blue cloth.
