Eccl. 10:1 As dead flies give perfume a bad smell,
so a little folly outweighs wisdom and honor.
2 The heart of the wise inclines to the right,
but the heart of the fool to the left.
3 Even as fools walk along the road,
they lack sense
and show everyone how stupid they are.

Ecclesiastes 10:1-3 (NIV 2011)
