Charles H. Spurgeon on Psalms 115:4

Their idols are silver and gold. Can there be anything more absurd than to expect assistance from them, since neither the materials of which they are formed, nor the forms which are given them by the hand of men possess the smallest portion of divinity so as to command respect for them? At the same time, the prophet tacitly indicates that the value of the material does not invest the idols with more excellence, so that they deserve to be more highly esteemed. Hence the passage may be translated adversatively, thus, Though they are of gold and silver, yet they are not gods, because they are the work of men's hands. John Calvin.
