Exodus 39:21

and all the vessels of the tabernacle and all its instruments: and the skins, even rams' skins dyed red, and the blue coverings, and the coverings of the other things, and the pins, and all the instruments for the works of the tabernacle of witness.

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.

They bound the breastplate by its rings to the rings of the ephod with a lace of blue, that it might be on the skillfully woven band of the ephod, and that the breastplate might not come loose from the ephod, as Yahweh commanded Moses.
