Exodus 28:22-29

22“You shall make chains for the breastplate at the end, like braided cords of pure gold.

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

24Then you shall put the two braided chains of gold in the two rings which are on the ends of the breastplate;

25and the other two ends of the two braided chains you shall fasten to the two settings, and put them on the shoulder straps of the ephod in the front.

26“You shall make two rings of gold, and put them on the two ends of the breastplate, on the edge of it, which is on the inner side of the ephod.

27And two other rings of gold you shall make, and put them on the two shoulder straps, underneath the ephod toward its front, right at the seam above the intricately woven band of the ephod.

28They shall bind the breastplate by means of its rings to the rings of the ephod, using a blue cord, so that it is above the intricately woven band of the ephod, and so that the breastplate does not come loose from the ephod.

29“So Aaron shall bear the names of the sons of Israel on the breastplate of judgment over his heart, when he goes into the holy place, as a memorial before the Lord continually.
