They bound the breastpiece by its rings to the rings of the ephod with a blue cord, so that it rested above the waistband of the ephod and the breastpiece did not come loose from the ephod, as Yahweh had commanded Moses.
In context
19They made two gold rings and put them on the two ends of the breastpiece, on the edge that faced the inside of the ephod. 20They made two more gold rings and put them on the two shoulder pieces of the ephod, below, at the front, close to the seam, above the waistband of the ephod. 21They bound the breastpiece by its rings to the rings of the ephod with a blue cord, so that it rested above the waistband of the ephod and the breastpiece did not come loose from the ephod, as Yahweh had commanded Moses. 22He made the robe of the ephod, the work of a weaver, entirely of blue. 23The opening of the robe, in its middle, was like the opening of a coat of armor, with a woven binding around the opening, so that it would not tear.
