Exodus 28:24-34

24 You shall put the two cords of gold in the two rings at the edges of the breastpiece;
25 the two ends of the two cords you shall attach to the two settings, and so attach it in front to the shoulder-pieces of the ephod.
26 You shall make two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod.
27 You shall make two rings of gold, and attach them in front to the lower part of the two shoulder-pieces of the ephod, at its joining above the decorated band of the ephod.
28 The breastpiece shall be bound by its rings to the rings of the ephod with a blue cord, so that it may lie on the decorated band of the ephod, and so that the breastpiece shall not come loose from the ephod.
29 So Aaron shall bear the names of the sons of Israel in the breastpiece of judgment on his heart when he goes into the holy place, for a continual remembrance before the Lord.
30 In the breastpiece of judgment you shall put the Urim and the Thummim, and they shall be on Aaron's heart when he goes in before the Lord; thus Aaron shall bear the judgment of the Israelites on his heart before the Lord continually.
31 You shall make the robe of the ephod all of blue.
32 It shall have an opening for the head in the middle of it, with a woven binding around the opening, like the opening in a coat of mail, so that it may not be torn.
33 On its lower hem you shall make pomegranates of blue, purple, and crimson yarns, all around the lower hem, with bells of gold between them all around—
34 a golden bell and a pomegranate alternating all around the lower hem of the robe.
