The Bible
Exodus 28
Aaron and his sons are to be consecrated and anointed to minister in the priest’s office—Aaron’s garments are to include a breastplate, an ephod, a robe, a coat, a miter, and a girdle—The breastplate of judgment is to contain twelve precious stones with the names of the tribes of Israel thereon—The Urim and Thummim are to be carried in the breastplate.
2And thou shalt make holy garments for Aaron thy brother for glory and for beauty.
5And they shall take gold, and blue, and purple, and scarlet, and fine linen.
9And thou shalt take two onyx stones, and grave on them the names of the children of Israel:
13¶ And thou shalt make ouches of gold;
18And the second row shall be an emerald, a sapphire, and a diamond.
19And the third row a ligure, an agate, and an amethyst.
22¶ And thou shalt make upon the breastplate chains at the ends of wreathen work of pure gold.
