Striving after the wind
(24) There is nothing better for a man than that he should eat and drink and make himself enjoy good in his labor. Even this, I have seen, is from the hand of God.
(25) For who can eat or who can have enjoyment any more than I can--apart from Him ?
(26) For to the person who pleases Him God gives wisdom and knowledge and joy; but to the sinner He gives the work of gathering and heaping up, that he may give to one who pleases God. This also is vanity and a striving after the wind and a feeding on it.
