Exodus 39:6-8

American Standard Version

⁶ And they wrought the onyx stones, inclosed in settings of gold, graven with the engravings of a signet, according to the names of the children of Israel. ⁷ And he put them on the shoulder-pieces of the ephod, to be stones of memorial for the children of Israel; as Jehovah commanded Moses.

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