He who labors works for himself, for his mouth craves it from him.
In all labor there is gain, but the talk of the lips tends only to poverty.
There is a way that seems right to a man, but the end of it is the ways of death.
An ungodly man plots evil, and his lips are like a burning fire.
If you are wise, you shall be wise for yourself; but if you scorn, you alone shall bear it.
All the labor of man is for his mouth, and yet the appetite is not filled.
