Exodus 28:22-28, 31-35

“Then make braided chains of pure gold for the Breastpiece, like cords. Make two rings of gold for the Breastpiece and fasten them to the two ends. Fasten the two golden cords to the rings at the ends of the Breastpiece. Then fasten the other ends of the two cords to the two settings of filigree, attaching them to the shoulder pieces of the Ephod in front. Then make two rings of gold and fasten them to the two ends of the Breastpiece on its inside edge facing the Ephod. Then make two more rings of gold and fasten them in the front of the Ephod to the lower part of the two shoulder pieces, near the seam above the decorated band. Fasten the Breastpiece in place by running a cord of blue through its rings to the rings of the Ephod so that it rests secure on the decorated band of the Ephod and won’t come loose.

“Make the robe for the Ephod entirely of blue, with an opening for the head at the center and a hem on the edge so that it won’t tear. For the edge of the skirts make pomegranates of blue, purple, and scarlet material all around and alternate them with bells of gold—gold bell and pomegranate, gold bell and pomegranate—all around the hem of the robe. Aaron has to wear it when he does his priestly work. The bells will be heard when he enters the Holy Place and comes into the presence of GOD, and again when he comes out so that he won’t die.
