Ecclesiastes 8:14-15

There 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; again, there are wicked men to whom it happeneth according to the work of the righteous: I said that this also is vanity. Then I commended mirth, because a man hath no better thing under the sun, than to eat, and to drink, and to be joyful: for that shall abide with him in his labor all the days of his life which God hath given him under the sun.
