Shemot 39:6-8

Orthodox Jewish Bible

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.

⁸ And he made the Choshen of artistic weaver’s work, like the workmanship of the Ephod; of zahav, turquoise, and purple, and scarlet wool, and fine twisted linen.
