Ecclesiastes 10:1-3

10:1 One dead fly makes the perfumer’s ointment give off a rancid stench,

so a little folly can outweigh much wisdom.

Wisdom Can Be Nullified By the Caprice of Rulers

10:2 A wise person’s good sense protects him,

but a fool’s lack of sense leaves him vulnerable.

10:3 Even when a fool walks along the road he lacks sense,

and shows everyone what a fool he is.
