Charles H. Spurgeon on Psalms 135:16

They have mouths. For their makers fashioned them like themselves. An opening is made where the mouth should be, and yet it is no mouth, for they eat not, they speak not. They cannot communicate with their worshippers; they are dumb as death. If they cannot even speak, they are not even so worthy of worship as our children at school. Jehovah speaks, and it is done: but these images utter never a word. Surely, if they could speak, they would rebuke their votaries. Is not their silence a still more powerful rebuke? When our philosophical teachers deny that God has made any verbal revelation of himself they also confess that their god is dumb. Eyes have they, but they see not. Who would adore a blind man —how can the heathen be so mad as to bow themselves before a blind image? The eyes of idols have frequently been very costly; diamonds have been used for that purpose; but of what avail is the expense, since they see nothing? If they cannot even see us, how can they know our wants, appreciate our sacrifices, or spy out for us the means of help! What a wretched thing, that a man who can see should bow down before an image which is blind! The worshipper is certainly physically in advance of his god, and yet mentally he is on a level with it; for assuredly his foolish heart is darkened, or he would not so absurdly play the feel.
