Exodus 28:17-21
And you shall mount on it four rows of stones; the first row shall be a row of ruby, topaz, and emerald;and the second row a turquoise, a sapphire, and a diamond;and the third row a jacinth, an agate, and an amethyst;and the fourth row a beryl, and an onyx, and a jasper; they shall be set in gold filigree.The stones shall be engraved according to the names of the sons of Israel: twelve, according to their names; they shall be like the engravings of a signet, each according to his name for the twelve tribes.
Exodus 39:6-14
They also made the onyx stones, set in gold filigree settings; they were engraved like the engravings of a signet, according to the names of the sons of Israel.And he placed them on the shoulder pieces of the ephod as memorial stones for the sons of Israel, just as the Lord had commanded Moses.And he made the breastpiece, the work of a skilled embroiderer, like the workmanship of the ephod: of gold and of violet, purple, and scarlet material and fine twisted linen.It was square; they made the breastpiece folded double, a span long and a span wide when folded double.And they mounted four rows of stones on it. The first row was a row of ruby, topaz, and emerald;and the second row, a turquoise, a sapphire, and a diamond;and the third row, a jacinth, an agate, and an amethyst;and the fourth row, a beryl, an onyx, and a jasper. They were set in gold filigree settings when they were mounted.The stones corresponded to the names of the sons of Israel; they were twelve, corresponding to their names, engraved with the engravings of a signet, each with its name for the twelve tribes.
