Forsomuch as a man should weary himself with wisdom, with understanding and opportunity, and yet be fain to leave his labours unto another, that never sweat for them. This is also a vain thing and a great misery.

There is one man, no more but himself alone, having neither child nor brother: yet is there no end of his careful travail, his eyes cannot be satisfied with riches. Yet, doth he not remember himself, and say, "For whom do I take such travail? For whose pleasure do I thus consume away my life?" This is also a vain and miserable thing.

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

The thing that hath been is named already, and known - that it is man himself: neither may he go to law with him that is mightier than he.

Because now that evil works are not hastily punished, the heart of man giveth himself over unto wickedness.

A doting fool thinketh, that every man doth as foolishly as himself.

But he that diggeth up a pit, shall fall therein himself; and whoso breaketh down the hedge, a serpent shall bite him.

The words out of a wise man's mouth are gracious, but the lips of a fool will destroy himself.
