Exodus 28:34-38

a golden bell and a pomegranate, a golden bell and a pomegranate, all around on the hem of the robe.

It shall be on Aaron when he ministers; and its sound shall be heard when he enters and leaves the Holy Place before the Lord, so that he will not die.

“You shall also make a plate of pure gold and engrave on it, like the engravings of a signet, ‘Holy to the Lord.’

You shall fasten it on a violet cord, and it shall be on the turban; it shall be at the front of the turban.

It shall be on Aaron’s forehead, and Aaron shall take away the guilt of the holy things which the sons of Israel consecrate, regarding all their holy gifts; and it shall always be on his forehead, so that they may be accepted before the Lord.
