With the work of an engraver in stone, [like] the engravings of a signet, shalt thou engrave the two stones with the names of the children of Israel: thou shalt make them to be set in ouches of gold.
ASV
With the work of an engraver in stone, like the engravings of a signet, shalt thou engrave the two stones, according to the names of the children of Israel: thou shalt make them to be inclosed in settings of gold.
