이사야 40:20의 인용 해설

ובחרשת denotes artisanship generally, as (Isaiah 40:20) “a clever artisan (חרש חכם)”. Onkelos, however, more closely defines the term each time it occurs in this verse and varies the definition he gives of them: the first he renders by אמנות and the second by נגרות, because the lapidary is called in Aramaic אמן, whilst the worker in wood is called נגר, and he therefore uses the abstract forms of these nouns to specify the particular kind of artisanship here intended.

and as strong as a lower millstone This clause is repetitious, meaning that his heart is as basic and permanent as the millstone that is placed under the upper millstone, for the upper millstone revolves and rotates and grinds, whereas the lower one does not move from its place because it is fastened to its place, so that it should not move. That is called פֶּלַח [רֶכֶב] as it is stated (Jud. 9:53): “And a certain woman cast an upper millstone: פֶּלַח רֶכֶב, upon Abimelech’s head.” The lower one is called פֶלַח תַּחתִּית the lower piece.
