Exodus 39:19-21

Darby Translation

¹⁹ And they made two rings of gold, and put [them] on the two ends of the breastplate, on the border thereof, which faceth the ephod inwards.

²⁰ And they made two rings of gold, and put them upon the two shoulder-pieces of the ephod underneath, to the front thereof, just by the coupling thereof, above the girdle of the ephod.

²¹ And they bound the breastplate with its rings to the rings of the ephod with lace of blue, that it might be above the girdle of the ephod, and that the breastplate might not be loosed from the ephod; as Jehovah had commanded Moses.
