'Toil' in the Bible
What does a man acquire from all his labor and from the anxiety that accompanies his toil on earth?
and also that everyone should eat and drink, and find enjoyment in all his toil, for these things are a gift from God.
Better is one handful with some rest than two hands full of toil and chasing the wind.
A man who is all alone with no companion, he has no children nor siblings; yet there is no end to all his toil, and he is never satisfied with riches. He laments, "For whom am I toiling and depriving myself of pleasure?" This also is futile and a burdensome task!
Just as he came forth from his mother's womb, naked will he return as he came, and he will take nothing in his hand that he may carry away from his toil.
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.
So I recommend the enjoyment of life, for there is nothing better on earth for a person to do except to eat, drink, and enjoy life. So joy will accompany him in his toil during the days of his life which God gives him on earth.
The toil of a stupid fool wears him out, because he does not even know the way to the city.
