Exodus 39:5-7

Young's Literal Translation

⁵ And the girdle of his ephod which [is] on it is of the same, according to its work, of gold, blue, and purple, and scarlet, and twined linen, as Jehovah hath commanded Moses.

⁶ And they prepare the shoham stones, set, embroidered [with] gold, opened with openings of a signet, by the names of the sons of Israel;

⁷ and he setteth them on the shoulders of the ephod -- stones of memorial for the sons of Israel, as Jehovah hath commanded Moses.
