Exodus 39:29-31

King James Version

²⁹ And a girdle of fine twined linen, and blue, and purple, and scarlet, of needlework; as the Lord commanded Moses.

³⁰ And they made the plate of the holy crown of pure gold, and wrote upon it a writing, like to the engravings of a signet, Holiness To The Lord.

³¹ And they tied unto it a lace of blue, to fasten it on high upon the mitre; as the Lord commanded Moses.
