Exodus 39
20 Ref And they made two rings of gold, and put them on the two shoulder-pieces of the ephod underneath, in the forepart thereof, close by the coupling thereof, above the skilfully woven band of the ephod.
21 Ref And they did bind the breastplate by the rings thereof unto the rings of the ephod with a lace of blue, that it might be upon the skilfully woven band of the ephod, and that the breastplate might not be loosed from the ephod; as Jehovah commanded Moses.
