Exodus 28:9-11

Revised Standard Version

⁹ And you shall take two onyx stones, and engrave on them the names of the sons of Israel, ¹⁰ six of their names on the one stone, and the names of the remaining six on the other stone, in the order of their birth. ¹¹ As a jeweler engraves signets, so shall you engrave the two stones with the names of the sons of Israel; you shall enclose them in settings of gold filigree.
