Ecclesiastes 5:18
“Behold that which I have seen: it is good and comely for one to eat and to drink, and to enjoy the good of all his labour that he taketh under the sun all the days of his life, which God giveth him: for it is his portion.”
And this also is a sore evil, that in all points as he came, so shall he go: and what profit hath he that hath laboured for the wind?
All his days also he eateth in darkness, and he hath much sorrow and wrath with his sickness.
Behold that which I have seen: it is good and comely for one to eat and to drink, and to enjoy the good of all his labour that he taketh under the sun all the days of his life, which God giveth him: for it is his portion.
Every man also to whom God hath given riches and wealth, and hath given him power to eat thereof, and to take his portion, and to rejoice in his labour; this is the gift of God.
For he shall not much remember the days of his life; because God answereth him in the joy of his heart.
