Shemot 39:4-6

Orthodox Jewish Bible

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

⁵ And the Cheishev (Belt) of his Ephod, which is upon it, was of the same according to the work thereof; of zahav, turquoise, and purple, and scarlet wool, and twisted linen; as Hashem commanded Moshe.

⁶ And they made the avnei shoham (onyx stones), set in settings of zahav, engraved, like chotam (signet ring) is engraved, according to the Shemot Bnei Yisroel.
