Albert Barnes Commentary Psalms 135:15-18

"The idols of the nations are silver and gold, The work of men`s hands. They have mouths, but they speak not; Eyes have they, but they see not; They have ears, but they hear not; Neither is there any breath in their mouths. They that make them shall be like unto them; Yea, every one that trusteth in them." — Psalms 135:15-18 (ASV)

The idols of the heathen are silver and gold ... - To show more fully the propriety of praising God, and him alone as God, the psalmist instituted a comparison between him and idols, showing that the gods worshipped by the pagans lacked every ground of claim to divine worship and homage. They were, after all that could be done to fashion, to decorate, and to adorn them, nothing but silver and gold, and could have no better claim to worship than silver and gold as such. They had, indeed, mouths, eyes, and ears, but they could neither speak, see, hear, nor breathe.

The passage here is substantially the same as in Psalms 115:4-8. One was evidently copied from the other, though in the latter the description is in some respects amplified; but which was the original it is impossible to determine. See the notes on that passage.
