and I have looked on all my works that my hands have done, and on the labour that I have laboured to do, and lo, the whole is vanity and vexation of spirit, and there is no advantage under the sun!

And who knoweth whether he is wise or foolish? yet he doth rule over all my labour that I have laboured at, and that I have done wisely under the sun! this also is vanity.

And I turned round to cause my heart to despair concerning all the labour that I laboured at under the sun.

For there is a man whose labour is in wisdom, and in knowledge, and in equity, and to a man who hath not laboured therein he giveth it -- his portion! Even this is vanity and a great evil.

For what hath been to a man by all his labour, and by the thought of his heart that he laboured at under the sun?

Sweet is the sleep of the labourer whether he eat little or much; and the sufficiency of the wealthy is not suffering him to sleep.
