Exodus 39:7 KJV

5And the curious girdle of his ephod, that was upon it, was of the same, according to the work thereof; of gold, blue, and purple, and scarlet, and fine twined linen; as the LORD commanded Moses.

6And they wrought onyx stones inclosed in ouches of gold, graven, as signets are graven, with the names of the children of Israel.

7And he put them on the shoulders of the ephod, that they should be stones for a memorial to the children of Israel; as the LORD commanded Moses.

8And he made the breastplate of cunning work, like the work of the ephod; of gold, blue, and purple, and scarlet, and fine twined linen.

9It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being doubled.
