A worker’s appetite works for him; his mouth urges him on.
All the toil of man is for his mouth, yet his appetite is not satisfied.
In all toil there is profit, but mere talk tends only to poverty.
If you are wise, you are wise for yourself; if you scoff, you alone will bear it.
There is a way that seems right to a man, but its end is the way to death.
A worthless man plots evil, and his speech is like a scorching fire.
