He that laboureth laboureth for himself; for his mouth craveth it of him.
In all labour there is profit: but the talk of the lips tendeth only to penury.
There is a way that seemeth right unto a man, but the end thereof are the ways of death.
An worthless man diggeth up evil: and in his lips there is as a burning fire.
If thou be wise, thou shalt be wise for thyself: but if thou scornest, thou alone shalt bear it.
All the labour of man is for his mouth, and yet the appetite is not filled.
