Ecclesiastes 5:17-19

All his days also he eateth in darkness, and he is sore vexed, and hath sickness and wrath. Behold, that which I have seen to be good and to be comely is for one to eat and to drink, and to enjoy good in all his labor, wherein he laboreth under the sun, all the days of his life which God hath given him: for this is his portion. Every man also to whom God hath given riches and wealth, and hath given him power to eat thereof, and to take his portion, and to rejoice in his labor—this is the gift of God.
