Leeser(i)
20 Therefore I turned about to cause my heart to give up thinking of all the toil wherewith I had toiled under the sun.
21 For there is many a man whose toil is in wisdom, and in knowledge, and with energy; yet to a man that hath not toiled therefore must he give it as his portion. Also this is vanity and a great evil.
22 For what doth a man obtain of all his toil, and of the torture of his heart, wherewith he toileth under the sun?
23 For all his days are full of pains, and vexation is mingled with his employment: yea, even in the night his heart taketh not rest. Also this is vanity.
