Exodus 28:28-30

New Century Version

²⁸ Join the rings of the chest covering to the rings of the holy vest with blue ribbon, connecting it to the woven belt so the chest covering will not swing out from the holy vest.

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.
