Exodus 28:37

“These are the garments which they shall make: a breastpiece and an ephod and a robe and a tunic of checkered work, a turban and a sash, and they shall make holy garments for Aaron your brother and his sons, in order for him to minister as priest to Me.

and you shall set the turban on his head and put the holy crown on the turban.

They made the plate of the holy crown of pure gold and wrote upon it with engraved writing as found on a signet, “Holy to Yahweh.”

In that day there will be inscribed on the bells of the horses, “Holy to Yahweh.” And the pots in the house of Yahweh will be like the bowls before the altar.
