Exodus 39:6-8

King James Version

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

⁷ And 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.

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