Ecclesiastes 2:20-23

²⁰Wherefore I ceased, and mine heart forsook for to travail further under the sun. (And so I ceased to study, and my heart did not desire to labour any more under the sun.)

²¹For why when another man travaileth in wisdom, and teaching, and busyness, he leaveth things gotten to an idle man; and therefore this is vanity, and great evil. (For though a person laboureth over something with wisdom, and knowledge, and diligence, he must leave all that he hath gotten to someone else, who did not labour over it; and so this is empty and futile, and a great evil.)

²²For why what shall it profit to a man of all his travail, and torment of spirit, with which he was tormented under the sun? (For what shall it profit a person for all his labour, and trials and tribulations, with which he was tormented under the sun?)

²³All his days be full of sorrows and mischiefs, and by night he resteth not in soul; and whether this is not vanity? (All his days be full of sorrows and mischiefs, and at night his soul resteth not; and is not this all empty and futile?)
