“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.”
Exodus 39:21 (WEB)
Context Reading
19They 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. 20They 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. 21They 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. 22He made the robe of the ephod of woven work, all of blue. 23The opening of the robe in the middle of it was like the opening of a coat of mail, with a binding around its opening, that it should not be torn.
