Shemot 28:9-11

Orthodox Jewish Bible

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).

¹¹ With the work of a charash even (engraver in gemstones), like the engravings of a chotam (signet ring), shalt thou engrave the two avanim with the Shemot Bnei Yisroel; thou shalt make them to be set in mishbetzot zahav (filigrees of gold).
