Exodus 28:36-38 - The Turban
36 And you shall make a plate of pure gold, and carve on it, like the engravings of a signet, HOLINESS TO JEHOVAH.
37 And you shall put a ribbon on it, and it shall be on the miter; to the front of the miter it shall be. 38 And it shall be on Aaron's forehead, so that Aaron may bear the iniquity of the holy things which will sanctify the sons of Israel in all their holy gifts. And it shall always be on his forehead, so that they may be accepted before Jehovah.
