Exodus 39:10

6They worked the onyx stones, enclosed in settings of gold, engraved with the engravings of a signet, according to the names of the children of Israel.

7He put them on the shoulder straps of the ephod, to be stones of memorial for the children of Israel, as the LORD commanded Moses.

8He made the breastplate, the work of a skillful workman, like the work of the ephod: of gold, of blue, purple, scarlet, and fine twined linen.

9It was square. They made the breastplate double. Its length was a span, and its width a span, being double.

10They set in it four rows of stones. A row of ruby, topaz, and beryl was the first row;

11and the second row, a turquoise, a sapphire, and an emerald;

12and the third row, a jacinth, an agate, and an amethyst;

13and the fourth row, a chrysolite, an onyx, and a jasper. They were enclosed in gold settings.

14The stones were according to the names of the children of Israel, twelve, according to their names; like the engravings of a signet, everyone according to his name, for the twelve tribes.
