Exodus 28:15

15 a“You shall make a breastpiece of judgment, in skilled work. In the style of the ephod you shall make it—of gold, blue and purple and scarlet yarns, and fine twined linen shall you make it.

Exodus 39:8-21

8 bHe made the breastpiece, in skilled work, in the style of the ephod, of gold, blue and purple and scarlet yarns, and fine twined linen. 9It was square. They made the breastpiece doubled, a span
A  span was about 9 inches or 22 centimeters
its length and a span its breadth when doubled.
10And they set in it four rows of stones. A row of sardius, topaz, and carbuncle was the first row; 11and the second row, an emerald, a sapphire, and a diamond; 12and the third row, a jacinth, an agate, and an amethyst; 13and the fourth row, a beryl, an onyx, and a jasper. They were enclosed in settings of gold filigree. 14There were twelve stones with their names according to the names of the sons of Israel. They were like signets, each engraved with its name, for the twelve tribes. 15And they made on the breastpiece twisted chains like cords, of pure gold. 16And they made two settings of gold filigree and two gold rings, and put the two rings on the two edges of the breastpiece. 17And they put the two cords of gold in the two rings at the edges of the breastpiece. 18They attached the two ends of the two cords to the two settings of filigree. Thus they attached it in front to the shoulder pieces of the ephod. 19Then they made two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod. 20And they made two rings of gold, and attached them in front to the lower part of the two shoulder pieces of the ephod, at its seam above the skillfully woven band of the ephod. 21And they bound the breastpiece by its rings to the rings of the ephod with a lace of blue, so that it should lie on the skillfully woven band of the ephod, and that the breastpiece should not come loose from the ephod, as the Lord had commanded Moses.

17 dHe put on righteousness as a breastplate,
and a helmet of salvation on his head;

and wrapped himself in ezeal as a cloak.

Revelation of John 9:17

17And this is how I saw the horses in my vision and those who rode them: they wore breastplates the color of fire and of sapphire
Greek hyacinth
and of sulfur, and the heads of the horses were klike lionsheads, and fire and smoke and sulfur came out of their mouths.
