Proverbs 16:26

A troublous soul disquieteth herself; for her own mouth hath brought her thereto.

All the labour that man taketh is for himself, and yet his desire is never filled after his mind.

If thou be wise, thy wisdom shall do thyself good: but if thou thinkest scorn thereof, it shall be thine own harm.

In every labour there is some profit; but only vain words bringeth forth penury.

and that ye study to be quiet, and to meddle with your own business, and to work with your own hands, as we commanded you:

Neither took we bread of any man for nought: but wrought with labour and travail night and day, because we would not be grievous to any of you:
