Exodus 28:22-28

22-28. Chains… rings This description shows in minute detail the manner in which the breastplate was securely fastened to the ephod . Josephus says that “whereas the rings were too weak of themselves to bear the weight of the stones, they made two other rings of a larger size, at the edge of that part of the breastplate which reached to the neck, and inserted into the very texture of the breastplate, to receive chains finely wrought, which connected them to the tops of the shoulders with golden bands, whose extremity turned backward and went into the ring on the prominent back part of the ephod; and this was for the security of the breastplate, that it might not fall out of its place . ”
