ps 115:5

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, Hab 2:18, Kg1 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, Dan 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their desires are before him, and their groanings are not hid from him; his eyes are on the righteous, and are never withdrawn from them.
