Exodus 28:28-30

Expanded Bible

²⁸ Join the rings of the ·chest covering [breastpiece] to the rings of the ·holy vest [ephod] with blue ·ribbon [cord], connecting it to the ·woven belt [embroidered waistband] so the ·chest covering [breastpiece] will not ·swing out [get loose] from the ·holy vest [ephod].

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 [breastpiece of judgment; 28:15]. This will be a continual reminder before the Lord. ³⁰ And put the Urim and Thummim [^Cdevices, probably lots, that were used to discern God’s will; the name means “light and truth”] inside the ·chest covering [breastpiece] 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.
