Shemot 39:2-4

Orthodox Jewish Bible

² And he [Bezalel] made the Ephod of zahav, turquoise, and purple, and scarlet wool, and twisted fine linen.

³ And they did hammer the zahav into thin sheets, and cut threads, to work into the turquoise, and into the purple, and into the fine linen, the artistic weaver’s work.

⁴ They made attaching ketefot (shoulder straps) for it, which were attached to its two [upper] ends.
