Exodus 39:1-3

Now from the violet, purple, and scarlet material they made finely woven garments for ministering in the Holy Place, as well as the holy garments which were for Aaron, just as the Lord had commanded Moses.

He made the ephod of gold and of violet, purple, and scarlet material, and fine twisted linen.

Then they hammered out gold sheets and cut them into threads to be woven in with the violet, the purple, and the scarlet material, and the fine linen, the work of a skilled embroiderer.
