Екклесиаст 2:21

"For there is a man who labours with wisdom, and knowledge, and ability; and to a man who has not laboured for it, must he leave it as his portion: also that is vain, and a great evil." Ewald renders: whose labour aims after wisdom. But בּח וטו do not denote obj. (for the obj. of עמל is certainly the portion which is to be inherited), but are particular designations of the way and manner of the labour. Instead of שׁעמל, there is used the more emphatic form of the noun: שׁעמלו, who had his labour, and performed it; Sa1 7:17, cf. Jer 9:5, Jer 9:6, "Thine habitation is in the midst of deceit," and Hitz. under Job 9:27. Kishron is not ἀνδρεία (lxx), manliness, moral energy (Elster), but aptness, ability, and (as a consequence connecting itself therewith) success, good fortune, thus skilfulness conducting to the end. בּו refers to the object, and יתּננּוּ to the result of the work; חלקו is the second obj.-accus., or, as we rather say, pred.-accus.: as his portion, viz., inheritance. That what one has gained by skill and good fortune thus falls to the lot of another who perhaps recklessly squanders it, is an evil all the greater in proportion to the labour and care bestowed on its acquisition.

Solomon having pronounced all vanity, and particularly knowledge and learning, which he was so far from giving himself joy of that he found the increase of it did but increase his sorrow, in this chapter he goes on to show what reason he has to be tired of this world, and with what little reason most men are fond of it. I. He shows that there is no true happiness and satisfaction to be had in mirth and pleasure, and the delights of sense (Ecc 2:1-11). II. He reconsiders the pretensions of wisdom, and allows it to be excellent and useful, and yet sees it clogged with such diminutions of its worth that it proves insufficient to make a man happy (Ecc 2:12-16). III. He enquires how far the business and wealth of this world will go towards making men happy, and concludes, from his own experience, that, to those who set their hearts upon it, "it is vanity and vexation of spirit," (Ecc 2:17-23), and that, if there be any good in it, it is only to those that sit loose to it (Ecc 2:24-26).

2:21 work wisely with knowledge and skill: Skill in work is an expression of wisdom (e.g., see Exod 31:1-5). • leave the fruit . . . to someone who hasn’t worked for it: A person who has little personal investment tends to waste it or take foolish risks.
