Exodus 28:36-39

36“Make a flower-shaped medallion out of pure gold, and engrave on it (as on a signet ring): Holy to the Lord.

37Fasten a violet cord to it, and tie it so that it’s on the front of the turban.

38It will be on Aaron’s forehead. He’s the one to be blamed for anything done wrong when the Israelites bring their holy offerings—whatever their gifts may be. The medallion must always be on Aaron’s forehead so that the Lord will accept their offerings.

39“Make the specially woven inner robe of fine linen. Make the turban of fine linen, but the belt should be embroidered with colored yarn.
