ECB(i)
17 And I hated life; because the work worked under the sun is evil to me; for all is vanity and gnawing of spirit.
18 Yes, I hated all the toil I toiled under the sun; because I leave it to humanity after me.
19 And who knows whether he be wise or fool? - and yet dominates over all the toil I toiled wherein I enwisened myself under the sun. This is also vanity.
20 I turned my heart around to quit all the toil I toiled under the sun.
21 For there is a human whose toil is in wisdom and in knowledge and in prosperity; yet he gives his allotment to a human who never toiled therein. This also is vanity and a great evil.
22 For what has humanity of all his toil and of the gnawing of his heart wherein he toiled under the sun?
23 For all his days are sorrows and his drudgery, vexation; yes, his heart lies not down in the night. This is also vanity.
