Exodus 28:11

מעשה חרש אבן means THE WORK OF AN ARTIFICER IN STONES. This word חרש is in close connection (i. e. in the construct state) with the word that follows it and therefore it is punctuated with Patach in its last syllable. Similar is, (Isaiah 44:13) “The חָרַשׁ עצים stretcheth out a line” i. e. the worker in wood. So, also, (Isaiah 44:12) “the worker in (חָרַשׁ) iron maketh an axe.” All these examples of חָרַשׁ are in close connection with the words that follows them and are therefore punctuated with Patach. פתוחי חותם LIKE THE ENGRAVINGS OF A SIGNET — Understand this as the Targum renders it: a distinct writing like the engraving of a signet-ring: the letters were incised in them just as one incises the seals of a ring which are used to seal letters — a clear and distinct writing. על שמות — This is the same as בשמות “with the names of”. מסבת משבצות SURROUNDED WITH SETTINGS [OF GOLD] — Thou shalt make the stones to be surrounded by gold settings: the meaning is that they should make as a setting for each stone a kind of indentation in the gold, of the same size as the stone and sink it in the setting; thus the setting surrounds the stone on all sides. That setting they attached to the shoulder-pieces of the ephod.

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 Yisra᾽el: thou shalt make them to be set in fixtures of gold.
