Exodus 28:22-29

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

23You shall make on the breastpiece two rings of gold, and shall put the two rings on the two ends of the breastpiece.

24You shall put the two twisted cords of gold in the two rings which are on the ends of the breastpiece.

25The other two ends of the two cords you shall fasten in the two filigree settings in front, putting them on the shoulder pieces of the ephod.

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

27You are to make two gold rings and attach them to the lower part of the two shoulder pieces of the ephod in front, close to the place where it is joined, above the skillfully woven sash of the ephod.

28They shall bind the breastpiece by its rings to the rings of the ephod with a blue cord, so that it will be above the skillfully woven sash of the ephod, so that the breastpiece will not come loose from the ephod.

29So Aaron shall carry the names of the sons of Israel (Jacob) in the breastpiece of judgment over his heart when he enters the Holy Place, to bring them in continual remembrance before the Lord.
