Jeremiah 5:21

Hear now this, O foolish people, and without understanding,
&c.] or, "heart" ^F1; (See Gill on Jeremiah 4:22): which have eyes, and see not; which have ears, and hear not;
like the idols they served, ( Psalms 115:4-8 ) . this is an upbraiding of them with their folly and stupidity, their want of common sense, their blindness and ignorance; notwithstanding they had the means of light and knowledge, the law, and the prophets.
