Exodus 28:22-29

22You shall make for the breastpiece twisted chains like cords, of pure gold.

23And you shall make for the breastpiece two rings of gold, and put the two rings on the two edges of the breastpiece.

24And you shall put the two cords of gold in the two rings at the edges of the breastpiece.

25The two ends of the two cords you shall attach to the two settings of filigree, and so attach it in front to the shoulder pieces of the ephod.

26You shall make two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod.

27And 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 seam above the skillfully woven band of the ephod.

28And they shall bind the breastpiece by its rings to the rings of the ephod with a lace of blue, so that it may lie on the skillfully woven band of the ephod, so that the breastpiece shall not come loose from the ephod.

29So 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, to bring them to regular remembrance before the Lord.
