Exodus 28:26-28

26. And thou shalt make two rings of gold, and thou shalt put them upon the two ends of the breastplate in the border thereof, which [is] in the side of the ephod inward. 27. And two [other] rings of gold thou shalt make, and shalt put them on the two sides of the ephod underneath, toward the forepart thereof, over against the [other] coupling thereof, above the curious girdle of the ephod. 28. And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a lace of blue, that [it] may be above the curious girdle of the ephod, and that the breastplate be not loosed from the ephod.
