Charles H. Spurgeon on Psalms 115:6

They have ears, but they hear not. The Psalmist might have pointed to the monstrous ears with which some heathen deities are disfigured, —truly they have ears; but no prayer of their rotaries, though shouted by a million voices, can ever be heard by them. How can gold and silver hear, and how can a rational being address petitions to one who cannot even hear his words? Noses have they, but they smell not. The Psalmist seems to heap together these sentences with something of the grim sardonic spirit of Elijah when he said, "Cry aloud: for he is a god; either he is talking, or he is pursuing, or he is on a journey, or peradventure he sleepeth, and must be awaked." In sacred scorn he mocks at those who burn sweet spices, and fill their temples with clouds of smoke, all offered to an image whose nose cannot perceive the perfume. He seems to point his finger to every part of the countenance of the image, and thus pours contempt upon the noblest part of the idol, if any part of such a thing can be noble even in the least degree.
