Exodus 28:34-38

A golden bell and a pomegranate, a golden bell and a pomegranate, upon the hem of the robe round about.

And it shall be upon Aaron to minister: and his sound shall be heard when he goeth in unto the holy place before the LORD, and when he cometh out, that he die not.

And thou shalt make a plate of pure gold, and grave upon it, like the engravings of a signet, HOLINESS TO THE LORD.

And thou shalt put it on a blue lace, that it may be upon the mitre; upon the forefront of the mitre it shall be.

And it shall be upon Aaron’s forehead, that Aaron may bear the iniquity of the holy things, which the children of Israel shall hallow in all their holy gifts; and it shall be always upon his forehead, that they may be accepted before the LORD.
