Ecclesiastes 8:14,15

There is a vanity which is done upon the earth Either by wicked potentates, who do commonly advance unworthy men, and oppress persons of the greatest virtue and merit: or, by God's providence, who sees it fit for many weighty reasons so to manage the affairs of the present world. To whom it happeneth, &c. Who meet with such usage as the worst of men deserve. There be wicked men to whom it happeneth Who, instead of those punishments which they deserve, receive those rewards which are due to virtuous men. This also is vanity This is a very unreasonable thing, if it be considered without respect unto another life, as it is here, where Solomon is discoursing of the vanity of the present life, and of the impossibility of finding satisfaction and happiness in it. Then I commended mirth Hebrew, השׂמחה, joy or gladness. Upon these considerations I concluded, that it was most advisable for a man not to perplex and torment himself with the thoughts of the seeming inequality of the dispensations of Divine Providence, and of the great disorders which are in the world, or with cares and fears about future temporal events, or with insatiable desires of worldly things, but quietly, cheerfully, and thankfully to enjoy the comforts which God gives him. See notes on Ecclesiastes 2:24; Ecclesiastes 3:12; for that shall abide with him of his labour, &c. This is the best advantage which he can make of this world's goods, as to the present life.
