⁸ And the Cheishev of his Ephod, which is upon it, shall be of the same, according to the work thereof; even of zahav, of turquoise, and purple, and scarlet wool, and twisted linen.

⁹ And thou shalt take two avnei shoham (onyx stones), and engrave on them the Shemot of the Bnei Yisroel:

¹⁰ Shisha of their Shemot on one even (stone), and the other Shemot of the shisha remaining on the other even (stone), according to toldot (in the order in which they were born).
