Exodus 39:21 WEB

¹⁹  They made two rings of gold, and put them on the two ends of the breastplate, on the edge of it, which was toward the side of the ephod inward.

²⁰  They made two rings of gold, and put them on the two shoulder-pieces of the ephod underneath, in the front of it, 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 Yahweh commanded Moses.

²²  He made the robe of the ephod of woven work, all of blue.

²³  The opening of the robe in the midst of it was like the opening of a coat of mail, with a binding around its opening, that it should not be torn.
