Exodus 39:3-5

Young's Literal Translation

³ and they expand the plates of gold, and have cut off wires to work in the midst of the blue, and in the midst of the purple, and in the midst of the scarlet, and in the midst of the linen -- work of a designer;

⁴ shoulder-pieces they have made for it, joining; at its two ends it is joined.

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.
