Context
19 They made two rings of gold, and put them on the two ends of the breastplate, on its edge, which was toward the side of the ephod inward.
20 They made two more rings of gold, and put them on the two shoulder straps of the ephod underneath, in its front, close by its coupling, above the skillfully woven band of the ephod.
21 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 the LORD commanded Moses.
