Jeremiah 5:4

Therefore I said, Surely these are poor, the prophet here interrupting himself to voice an objection to the Lord; they are foolish, acting foolishly on account of their ignorance; for they know not the way of the Lord nor the judgment of their God. The prophet assumes that only the untaught poor are guilty of such depravity, and that a better state of affairs may be expected in the higher ranks of society.
