יֹֽצְרֵי־פֶ֤סֶל כֻּלָּם֙ תֹּ֔הוּ וַחֲמוּדֵיהֶ֖ם בַּל־יוֹעִ֑ילוּ וְעֵדֵיהֶ֣ם הֵׄ֗מָּׄהׄ בַּל־יִרְא֛וּ וּבַל־יֵדְע֖וּ לְמַ֥עַן יֵבֹֽשׁוּ׃
They that fashion a graven image are all of them vanity, And their delectable things shall not profit; And their own witnesses see not, nor know; That they may be ashamed.
Rashi on Isaiah
and they are their witnesses The idols are witnesses of the shame of their worshipers, for we see that they neither see nor know, yet they were worshiping them.
Ibn Ezra on Isaiah
They that make a graven image, are all of them vanity. They themselves as well as their images are vanity.
