NASB
"Throughout his life he also eats in darkness with great vexation, sickness and anger."
— Ecclesiastes 5:17, NASB
“All his days also he eateth in darkness, and he hath much sorrow and wrath with his sickness.”
“All his days also he eateth in darkness, and he is sore vexed, and hath sickness and wrath. ”
“All his days he also eats in darkness, he is frustrated, and has sickness and wrath.”
“Surely, he ate in darkness every day of his life, and he suffered greatly with sickness and anger.”
“This therefore hath seemed good to me, that a man should eat and drink, and enjoy the fruit of his labour, wherewith he hath laboured under the sun, all the days of his life, which God hath given him: and this is his portion.”
“All his days are in the dark, and he has much sorrow, pain, disease, and trouble.”
“All his days also he eateth in darkness, and he hath much sorrow and wrath with his sickness.”
When those riches were lost through a bad investment and he had fathered a son, then there was nothing to support him.
As he had come naked from his mother's womb, so will he return as he came. He will take nothing from the fruit of his labor that he can carry in his hand.
This also is a grievous evil--exactly as a man is born, thus will he die. So what is the advantage to him who toils for the wind?
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.
For he will not often consider the years of his life, because God keeps him occupied with the gladness of his heart.
