Exodus 28:36–37

“You shall make a plate of pure gold and engrave on it, like the engraving of a signet, ‘Holy to the Lord.’ And you shall fasten it on the turban by a cord of blue. It shall be on the front of the turban.

“Make a plate of pure gold and engrave on it as on a seal: holy to the Lord. Fasten a blue cord to it to attach it to the turban; it is to be on the front of the turban.

“You are to make a pure gold medallion and engrave it, like the engraving of a seal: Holy to the Lord. Fasten it to a cord of blue yarn so it can be placed on the turban; the medallion is to be on the front of the turban.

“Next make a medallion of pure gold, and engrave it like a seal with these words: Holy to the Lord. Attach the medallion with a blue cord to the front of Aaron’s turban, where it must remain.

“And you will make a pure gold rosette, and you will engrave on it with seal engravings: “A holy object for Yahweh.” And you will place it on a blue cord, and it will be on the turban, at the front of the turban it will be.

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.
