Exodus 28:37-39

International Standard Version

³⁷ You are to put it on a blue cord and place it on the turban. It is to be on the front of the turban ³⁸ and worn on Aaron’s forehead in order to take away any guilt contained in the holy things which the Israelis consecrate as holy gifts. It is to remain on his forehead continuously, so they may be accepted in the Lord’s presence.

³⁹ “You are to weave the checkered tunic of fine linen, you are to make a turban of fine linen, and you are to make an embroidered sash.
