Exodus 28:36-38

New Catholic Bible

³⁶ “You are to make a plate of pure gold and engrave ‘Holy to the Lord’ on it as one engraves a signet ring. ³⁷ Attach it with a blue cord to the front part of the turban. ³⁸ It will be on Aaron’s forehead, so that Aaron may carry the weight of whatever guilt the children of Israel may incur in the holy things, when they consecrate their holy offerings. He will always wear it on his forehead so that they may be pleasing to the Lord.
