Ecclesiastes 2:20-21

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.)
