Exodus 39:3-13

3 And they beat the gold into thin plates and cut it into wires to work it in the blue and in the purple and in the scarlet and in the fine linen, with cunning work.
4 They made the shoulder pieces for it to couple it together; by the two edges was it coupled together.
5 And the special girdle of his ephod, that was over it, was of the same, according to the work thereof: of gold, blue, purple, scarlet, and fine twined linen as the LORD had commanded Moses.
6 And they wrought onyx stones inclosed in settings of gold, graven, as seals are graven, with the names of the sons of Israel.
7 And he put them on the shoulders of the ephod that they should be stones for a memorial to the sons of Israel, as the LORD had commanded Moses.
8 He also made the pectoral of cunning work, like the work of the ephod of gold, blue, purple, scarlet, and fine twined linen.
9 It was square; they made the pectoral double; a span was the length thereof and a span the breadth thereof, being doubled.
10 And they set in it four orders of stones. The order was a ruby, an emerald, and a chrysolite: this was the first order.
11 The second order, a carbuncle, a sapphire, and a diamond.
12 The third order, a topaz, a turquoise, and an amethyst.
13 And the fourth order, a tarshish (or beryl), an onyx, and a jasper; they were set and inclosed in their settings of gold.
