'Labor' in the Bible

I saw that all labor and all skillful work is due to a man’s jealousy of his friend. This too is futile and a pursuit of the wind.

Here is what I have seen to be good: it is appropriate to eat, drink, and experience good in all the labor one does under the sun during the few days of his life God has given him, because that is his reward.

God has also given riches and wealth to every man, and He has allowed him to enjoy them, take his reward, and rejoice in his labor. This is a gift of God,

All man’s labor is for his stomach,yet the appetite is never satisfied.

So I commended enjoyment because there is nothing better for man under the sun than to eat, drink, and enjoy himself, for this will accompany him in his labor during the days of his life that God gives him under the sun.
