Ecclesiastes 10:1-3

International Children’s Bible

10 Dead flies will make even perfume smell bad.
    In the same way, a little foolishness can ruin
    a wise man’s fame for wisdom.
² A wise man’s heart leads him in the right way.
    But the heart of a foolish person leads him in the wrong way.
³ A foolish person is not wise.
    It shows in everything he does.
Even as he walks along the road,
    he shows everyone how stupid he is.
