He that labors labors for himself; for his mouth craves it of him.
In all labor there is profit: but the talk of the lips leads only to poverty.
There is a way that seems right unto a man, but the end thereof are the ways of death.
An ungodly man digs up evil: and in his lips there is as a burning fire.
If you are wise, you shall be wise for yourself: but if you scoff, you alone shall bear it.
All the labor of man is for his mouth, and yet the appetite is not filled.
