And I applied my heart to seek and search out by wisdom concerning all that is done under the heavens: this grievous occupation hath God given to the children of men to weary themselves therewith.

I made me ponds of water, to water therewith the wood, where the trees are reared.

I have seen the travail which God hath given to the sons of men to be exercised therewith.

Whoso heweth out stones shall be hurt therewith; and he that cleaveth wood is endangered thereby.
