C. F. Keil and Franz Delitzsch on Deuteronomy 4:28

Deu 4:28

There among the heathen they would be obliged to serve gods that were the work of men’s hands, gods of wood and stone, that could neither hear, nor eat, nor smell, i.e., possessed no senses, showed no sign of life. What Moses threatens here, follows from the eternal laws of the divine government. The more refined idolatry of image-worship leads to coarser and coarser forms, in which the whole nature of idol-worship is manifested in all its pitiableness. “When once the God of revelation is forsaken, the God of reason and imagination must also soon be given up and make way for still lower powers, that perfectly accord with the I exalted upon the throne, and in the time of pretended 'illumination' to atheism and materialism also” (Schultz).
