מִֽי־יָצַ֥ר אֵ֖ל וּפֶ֣סֶל נָסָ֑ךְ לְבִלְתִּ֖י הוֹעִֽיל׃
誰會塑造神明，鑄造毫無益處的雕像呢？
Rashi
molded Heb. נָסָךְ, an expression of pouring and a molten image (מַסֵּכָה). The ‘nun’ in the word is a radical sometimes omitted, e.g., the ‘nun’ of נשך, biting, and of נגף, plaguing.
Ibn Ezra
Who hath formed, etc. Is there any thoughtlessness like this, to attempt to form a god? God. So called in the sense of him who formed the image.
