Exodus 39:2-5

2Bezalel made the ephod of gold, and of blue, purple, and scarlet fabric, and fine twisted linen.

3Then Bezalel and Oholiab hammered the gold [into thin sheets] and cut it into threads to work into the blue, purple, and scarlet fabric, and into the fine linen, the work of a skilled craftsman.

4They made attaching shoulder pieces for the ephod; it was attached at its two [upper] edges.

5The skillfully woven sash with which to bind it, which was on the ephod [to hold it in place], was like its workmanship, of the same material: of gold and of blue, purple, and scarlet fabric, and fine twisted linen, just as the Lord had commanded Moses.
