Ecclesiastes 5:17-19 New English Translation (NET Bible)
17 Surely, he ate in darkness every day of his life,
and he suffered greatly with sickness and anger.
Enjoy the Fruit of Your Labor
18 I have seen personally what is the only beneficial and appropriate course of action for people:
to eat and drink, and find enjoyment in all their hard work on earth
during the few days of their life that God has given them,
for this is their reward.
19 To every man whom God has given wealth and possessions,
he has also given him the ability
to eat from them, to receive his reward, and to find enjoyment in his toil;
these things are the gift of God.
