Ecclesiastes 2:26 - Matthew Poole's English Annotations on the Holy Bible

That is good in his sight; who not only seems to be good to men, as many bad men do, but is really and sincerely good. Or, who pleaseth him, as this phrase is rendered, Ecclesiastes 7:26, and oft elsewhere; whereby he seems to intimate the reason why he found no more comfort in his labours, because his ways had been very displeasing to God, and therefore God justly denied him that gift. Wisdom and knowledge, to direct him how to use his comforts aright, that so they may be blessings, and not snares and curses to him. Joy; a thankful and contented mind with his portion. He giveth travail, to gather and to heap up; he giveth him up to insatiable desires, and wearisome labours, to little or no purpose. That he may give to him that is good before God; that he may have no comfort in them, but leave them to others, yea, to such as he least expected or desired, to good and virtuous men, into whose hands his estate falls by the wise and all-disposing providence of God.
