They have mouths - They are shaped like people, but have none of the attributes of intelligent beings.

They have mouths, but they speak not,.... These idols are carved with mouths, but they make no use of them; if any cry to them for they cannot answer them, nor save them from their troubles. Baal's priests cried to their idol, but was no voice heard, nor answer returned; they are rightly called dumb idols, Habakkuk 2:18, 1-Kings 18:26, but our God in the heavens, when his people cry to him, he answers them, and sends them relief; and tells them his grace is sufficient for them, and so they find it to be.
Eyes have they, but they see not; they are made with eyes in their heads, but cannot see with them; they cannot see their worshippers, nor what they bring to them; neither their persons nor their wants, Daniel 5:23, but our God and Father in heaven, he sees in secret the persons and hearts of his people; their desires are before him, and their groanings are not hid from him; his eyes are on the righteous, and are never withdrawn from them.
