Ecclesiastes 5:12-20 New Revised Standard Version (NRSV)
12 Sweet is the sleep of laborers, whether they eat little or much; but the surfeit of the rich will not let them sleep.
13 There is a grievous ill that I have seen under the sun: riches were kept by their owners to their hurt, 14 and those riches were lost in a bad venture; though they are parents of children, they have nothing in their hands. 15 As they came from their mother’s womb, so they shall go again, naked as they came; they shall take nothing for their toil, which they may carry away with their hands. 16 This also is a grievous ill: just as they came, so shall they go; and what gain do they have from toiling for the wind? 17 Besides, all their days they eat in darkness, in much vexation and sickness and resentment.
18 This is what I have seen to be good: it is fitting to eat and drink and find enjoyment in all the toil with which one toils under the sun the few days of the life God gives us; for this is our lot. 19 Likewise all to whom God gives wealth and possessions and whom he enables to enjoy them, and to accept their lot and find enjoyment in their toil—this is the gift of God. 20 For they will scarcely brood over the days of their lives, because God keeps them occupied with the joy of their hearts.
