Behold, all his fellows shall be ashamed: and the workmen, they are of men: let them all be gathered together, let them stand up; yet they shall fear, and they shall be ashamed together.
Behold, all his fellows shall be ashamed - the associates of him who makes an idol, or of the idol, become such a vain thing as the idol itself-its fellow and counterpart (see Deuteronomy 7:26; Psalms 115:8; Hosea 4:17).
The workmen, they (are) of men - they are mortal men themselves; what better, then, can the idol be than its maker?
Let them all be gathered together, let them stand up - as in a court of justice, to try the issue between God and them (note, Isaiah 41:1; Isaiah 41:21).
(Yet) they shall fear - "yet," wrongly inserted in the English version. The issue of the trial shall be, "they shall fear," etc.
