Ecclesiastes 5:17-20

All his days he also eats in darkness, And he has much sorrow and sickness and anger. Here is what I have seen: It is good and fitting for one to eat and drink, and to enjoy the good of all his labor in which he toils under the sun all the days of his life which God gives him; for it is his heritage. As for every man to whom God has given riches and wealth, and given him power to eat of it, to receive his heritage and rejoice in his labor—this is the gift of God. For he will not dwell unduly on the days of his life, because God keeps him busy with the joy of his heart.
