The appetite of the laboring man labors for him, for his mouth urges him.
All the labor of man is for his mouth, and yet the appetite is not filled.
In all labor there is profit, but the talk of the lips [tends] only to poverty.
If thou are wise, thou are wise for thyself. And if thou scoff, thou alone shall bear it.
There is a way which seems right to a man, but the end thereof are the ways of death.
A worthless man devises mischief, and in his lips there is as a scorching fire.
