Ecclesiastes 5:17-19

Throughout his life he also eats in darkness with great vexation, sickness and anger. Here is what I have seen to be good and fitting: to eat, to drink and enjoy oneself in all one’s labor in which he toils under the sun during the few years of his life which God has given him; for this is his reward. Furthermore, as for every man to whom God has given riches and wealth, He has also empowered him to eat from them and to receive his reward and rejoice in his labor; this is the gift of God.
