Ecclesiastes 1–2 (NKJV)
1 The words of the Preacher, the son of David, king in Jerusalem.
2 “Vanity of vanities,” says the Preacher;
“Vanity of vanities, all is vanity.”
…
24 Nothing is better for a man than that he should eat and drink, and that his soul should enjoy good in his labor. This also, I saw, was from the hand of God. 25 For who can eat, or who can have enjoyment, more than I? 26 For God gives wisdom and knowledge and joy to a man who is good in His sight; but to the sinner He gives the work of gathering and collecting, that he may give to him who is good before God. This also is vanity and grasping for the wind.
