Exodus 39:29-31

New Century Version

²⁹ Then they made the cloth belt of fine linen, and blue, purple, and red thread, and designs were sewn onto it, just as the Lord had commanded Moses.

³⁰ They made a strip of pure gold, which is the holy crown, and carved these words in the gold, as one might carve on a seal: “Holy to the Lord.” ³¹ Then they tied this flat piece to the turban with a blue ribbon, as the Lord had commanded Moses.
