Exodus 39:1-6

1 And of the blue and purple and scarlet they made clothes of service to do service in the holy place, and made the holy garments for Aaron, as the LORD commanded Moses.
2 And he made the ephod of gold, blue and purple and scarlet, and finetwined linen.
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 skillful work.
4 They made shoulder pieces for it to couple it together; by the two edges was it coupled together.
5 And the embroidered girdle of his ephod that was upon it was of the same, according to the work thereof: of gold, blue and purple and scarlet, and finetwined linen, as the LORD commanded Moses.
6 And they wrought onyx stones enclosed in clasps of gold, graven as signets are graven, with the names of the children of Israel.
