Exodus 39:7-17

7 He put them on the shoulder-pieces of the ephod, to be stones of memorial for the children of Israel, as Yahweh commanded Moses.
8 He 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.
9 It was square. They made the breastplate double. Its length was a span, and its breadth a span, being double.
10 They set in it four rows of stones. A row of ruby, topaz, and beryl was the first row;
11 and the second row, a turquoise, a sapphire, and an emerald;
12 and the third row, a jacinth, an agate, and an amethyst;
13 and the fourth row, a chrysolite, an onyx, and a jasper. They were enclosed in gold settings.
14 The 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.
15 They made on the breastplate chains like cords, of braided work of pure gold.
16 They made two settings of gold, and two gold rings, and put the two rings on the two ends of the breastplate.
17 They put the two braided chains of gold in the two rings at the ends of the breastplate.
