Exodus 28:5-8

5And they shall take gold, and blue, and purple, and scarlet, and fine linen.

6And they shall make the ephod of gold, of blue, and of purple, of scarlet, and fine twined linen, with skilful work. 7It shall have its two shoulderpieces joined at its two edges; and so it shall be joined together. 8And the beautifully woven band of the ephod, which is upon it, shall be of the same, according to its work; even of gold, of blue, and purple, and scarlet, and fine twined linen.1
