Rashi on Isaiah
Behold, all his colleagues of that fashioner and molder of graven images, who join him to worship his creation and his molten image, shall be ashamed.
Ibn Ezra on Isaiah
His fellows. The priests of Baal, or the artificers of the idols; the latter explanation is the better.
Rashi on Isaiah
and they are smiths those fashioners and molders, and they are of men, surely their creation is vanity.
