Exodus 39:11

And of the blue, and purple, and scarlet, they made cloths of service, to do service in the holy place, and made the holy garments for Aaron; as the LORD commanded Moses.

And he made the ephod of gold, blue, and purple, and scarlet, and fine twined linen.

And they did 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.

They made shoulderpieces for it, to couple it together: by the two edges was it coupled together.
