Exodus 39:3-7

3They hammered the gold into thin plates, and cut it into threads, to work it in with the blue, purple and scarlet, within the fine linen, the work of a skillful craftsman.

4Then they made shoulder pieces for it, joined together at the two ends.

5The artfully woven band on the ephod, with which to gird it, was of the same piece and the same kind of workmanship of gold, blue, purple, scarlet and finely twisted linen, as Adonai commanded Moses.

6They placed the onyx stones, enclosed in settings of gold, etched with the engravings of a signet seal, according to the names of Bnei-Yisrael.

7He put them on the shoulder pieces of the ephod, to be memorial stones for Bnei-Yisrael, as Adonai commanded Moses.
