Ecclesiastes 10:1-3

Lexham English Bible

10 Dead flies cause a bad smell and ruin^[a] the ointment of the perfumer.
    So also a little folly outweighs wisdom and honor.
² The heart of the wise inclines to his right,
    but the heart of the fool inclines to his left.
³ Even when the fool walks along the road, he lacks sense;
    he tells everyone that he is a fool.
