Exodus 28:6-8

And they shall make the ephod of gold, of blue, and purple, scarlet, and fine twined linen, the work of the skilful workman. It shall have two shoulder-pieces joined to the two ends thereof, that it may be joined together. And the skilfully woven band, which is upon it, wherewith to gird it on, shall be like the work thereof and of the same piece; of gold, of blue, and purple, and scarlet, and fine twined linen.
