Shemot 39:5-7

Orthodox Jewish Bible

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.

⁷ And he fastened them upon the Kitfot HaEphod, that they should be Avnei Zikaron (Memorial Stones) unto the Bnei Yisroel; as Hashem commanded Moshe.
