And they did bind the breastplate by his rings unto the rings of the ephod with a lace of blue, that it might be above the curious girdle of the ephod, and that the breastplate might not be loosed from the ephod; as the LORD commanded Moses.
So they attached the breastplate to the ephod using a blue lace, placing it over the decorative belt and making sure it stayed securely in place, just like the LORD told Moses.
