Exodus 39:6-14

6And they wrought the onyx stones, inclosed in settings of gold, graven with the engravings of a signet, according to the names of the children of Israel. 7And he put them on the shoulder-pieces of the ephod, to be stones of memorial for the children of Israel; as Jehovah commanded Moses.

8And he made the breastplate, the work of the skilful workman, like the work of the ephod; of gold, of blue, and purple, and scarlet, and fine twined linen. 9It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being double. 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 inclosed in inclosings of gold in their settings. 14And 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 according to his name, for the twelve tribes.
