Exodus 39:1-5 ESV
From the blue and purple and scarlet yarns they made finely woven garments, for ministering in the Holy Place. They made the holy garments for Aaron, as the LORD had commanded Moses. He made the ephod of gold, blue and purple and scarlet yarns, and fine twined linen. And they hammered out gold leaf, and he cut it into threads to work into the blue and purple and the scarlet yarns, and into the fine twined linen, in skilled design. They made for the ephod attaching shoulder pieces, joined to it at its two edges. And the skillfully woven band on it was of one piece with it and made like it, of gold, blue and purple and scarlet yarns, and fine twined linen, as the LORD had commanded Moses.
