Exodus 39:2-7

2They made the ephod of gold, and of blue, purple and scarlet yarn, and of finely twisted linen. 3They hammered out thin sheets of gold and cut strands to be worked into the blue, purple and scarlet yarn and fine linen—the work of skilled hands. 4They made shoulder pieces for the ephod, which were attached to two of its corners, so it could be fastened. 5Its skillfully woven waistband was like it—of one piece with the ephod and made with gold, and with blue, purple and scarlet yarn, and with finely twisted linen, as the Lord commanded Moses. 6They mounted the onyx stones in gold filigree settings and engraved them like a seal with the names of the sons of Israel. 7Then they fastened them on the shoulder pieces of the ephod as memorial stones for the sons of Israel, as the Lord commanded Moses.
