Exodus 39:6-8

Revised Geneva Translation

⁶ And they set two onyx stones, enclosed in settings of gold, and engraved (as signets are engraved) with the names of the sons of Israel.

⁷ And he put them on the shoulder pieces of the ephod—stones for a memorial to the sons of Israel—as the LORD had commanded Moses.

⁸ Also, they made the breastplate of skillful work, like the work of the ephod: of gold, blue silk, and purple, and scarlet, and fine-twined linen.
