Idle Idols

The denunciation of idols is a common characteristic of Psalms.  This is necessary because these people lived in the midst of idolatry where the scorning of idol-deities was constantly needed.

In the Psalm there is a contrast in the powerful God and the powerless idols.  It says of God. "he hath done whatsoever he pleased."  But all that could be said of the idols is:
They have mouths, but they speak not.
They have ears, but they hear not.
Noses have they, but they smell not.
They have hands, but the handle not.
Feet have they, but they walk not.
Idle idols they have the organs, but not the sensibilities.
They are the deified representations of a people's own frailties and passions.  And a study of a nation's gods will give you a nation's history.
Idols are only "the work of men's hands."  Having been made by man, they are inferior to him; and if there should be any worshiping of either, the idols ought to worship man.  So to make idolatry all the worse, it is practiced in reverse.
