Leviticus 8:8

And thou shalt make the breastplate of judgment with cunning work; after the work of the ephod thou shalt make it; of gold, of blue, and of purple, and of scarlet, and of fine twined linen, shalt thou make it. Foursquare it shall be being doubled; a span shall be the length thereof, and a span shall be the breadth thereof. And thou shalt set in it settings of stones, even four rows of stones: the first row shall be a sardius, a topaz, and a carbuncle: this shall be the first row. And the second row shall be an emerald, a sapphire, and a diamond. And the third row a ligure, an agate, and an amethyst. And the fourth row a beryl, and an onyx, and a jasper: they shall be set in gold in their inclosings. And the stones shall be with the names of the children of Israel, twelve, according to their names, like the engravings of a signet; every one with his name shall they be according to the twelve tribes. And thou shalt make upon the breastplate chains at the ends of wreathed work of pure gold. And thou shalt make upon the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate. And thou shalt put the two wreathed chains of gold in the two rings which are on the ends of the breastplate. And the other two ends of the two wreathed chains thou shalt fasten in the two ouches, and put them on the shoulderpieces of the ephod before it. And thou shalt make two rings of gold, and thou shalt put them upon the two ends of the breastplate in the border thereof, which is in the side of the ephod inward. And two other rings of gold thou shalt make, and shalt put them on the two sides of the ephod underneath, toward the forepart thereof, over against the other coupling thereof, above the curious girdle of the ephod. And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a lace of blue, that it may be above the curious girdle of the ephod, and that the breastplate be not loosed from the ephod. And Aaron shall bear the names of the children of Israel in the breastplate of judgment upon his heart, when he goeth in unto the holy place, for a memorial before the LORD continually.

And he made the breastplate of cunning work, like the work of the ephod; of gold, blue, and purple, and scarlet, and fine twined linen. It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being doubled. And they set in it four rows of stones: the first row was a sardius, a topaz, and a carbuncle: this was the first row. And the second row, an emerald, a sapphire, and a diamond. And the third row, a ligure, an agate, and an amethyst. And the fourth row, a beryl, an onyx, and a jasper: they were inclosed in ouches of gold in their inclosings. And the stones were according to the names of the children of Israel, twelve, according to their names, like the engravings of a signet, every one with his name, according to the twelve tribes. And they made upon the breastplate chains at the ends, of wreathed work of pure gold. And they made two ouches of gold, and two gold rings; and put the two rings in the two ends of the breastplate. And they put the two wreathed chains of gold in the two rings on the ends of the breastplate. And the two ends of the two wreathed chains they fastened in the two ouches, and put them on the shoulderpieces of the ephod, before it. And they made two rings of gold, and put them on the two ends of the breastplate, upon the border of it, which was on the side of the ephod inward. And they made two other golden rings, and put them on the two sides of the ephod underneath, toward the forepart of it, over against the other coupling thereof, above the curious girdle of the ephod. And they did bind the breastplate by his rings unto the rings of the ephod with a lace of blue, that it might be above the curious girdle of the ephod, and that the breastplate might not be loosed from the ephod; as the LORD commanded Moses.

Set me as a seal upon thine heart, as a seal upon thine arm: for love is strong as death; jealousy is cruel as the grave: the coals thereof are coals of fire, which hath a most vehement flame.

For he put on righteousness as a breastplate, and an helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloak.

Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;

But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation.
