Exodus 39:26 (KJV)

And they did bind the breastplate by his rings unto the rings of the ephod with a lace of blue, that it might be above the curious girdle of the ephod, and that the breastplate might not be loosed from the ephod; as the LORD commanded Moses.

And he made the robe of the ephod of woven work, all of blue.

And there was an hole in the midst of the robe, as the hole of an habergeon, with a band round about the hole, that it should not rend.

And they made upon the hems of the robe pomegranates of blue, and purple, and scarlet, and twined linen.

And they made bells of pure gold, and put the bells between the pomegranates upon the hem of the robe, round about between the pomegranates;

And they made coats of fine linen of woven work for Aaron, and for his sons,

And a mitre of fine linen, and goodly bonnets of fine linen, and linen breeches of fine twined linen,

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

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.

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