Ecclesiastes 8:14-17

14There is a vanity which is done upon the earth; that there are righteous [men] unto whom it happeneth according to the work of the wicked; and there are wicked [men] to whom it happeneth according to the work of the righteous. I said that this also is vanity. 15And I commended mirth, because there is nothing better for man under the sun than to eat, and to drink, and to be merry; for that shall abide with him of his labour the days of his life, which 1God hath given him under the sun. 16When I applied my heart to know wisdom, and to see the business that is done upon the earth (for also there is that neither day nor night seeth sleep with his eyes), 17then I saw that all [is] the work of 2God, [and] that man cannot find out the work that is done under the sun: because however man may labour to seek [it] out, yet doth he not find [it]; and even, if a wise [man] think to know [it], he shall not be able to find [it] out.
