'Days' in the Bible

I explored with my mind how to let my body enjoy life with wine and how to grasp folly—my mind still guiding me with wisdom—until I could see what is good for people to do under heaven during the few days of their lives.

For, just like the fool, there is no lasting remembrance of the wise man, since in the days to come both will be forgotten. How is it that the wise man dies just like the fool?

For all his days are filled with grief, and his occupation is sorrowful; even at night, his mind does not rest. This too is futile.

What is more, he eats in darkness all his days, with much sorrow, sickness, and anger.

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.

for he does not often consider the days of his life because God keeps him occupied with the joy of his heart.

For who knows what is good for man in life, in the few days of his futile life that he spends like a shadow? Who can tell man what will happen after him under the sun?

Don’t say, “Why were the former days better than these?”since it is not wise of you to ask this.

However, it will not go well with the wicked, and they will not lengthen their days like a shadow, for they are not reverent before God.

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.

Enjoy life with the wife you love all the days of your fleeting life, which has been given to you under the sun, all your fleeting days. For that is your portion in life and in your struggle under the sun.

Send your bread on the surface of the waters,for after many days you may find it.

Indeed, if a man lives many years,let him rejoice in them all,and let him remember the days of darkness, since they will be many.All that comes is futile.

Rejoice, young man, while you are young,and let your heart be glad in the days of your youth.And walk in the ways of your heartand in the sight of your eyes;but know that for all of these things God will bring you to judgment.

So remember your Creator in the days of your youth:Before the days of adversity come,and the years approach when you will say,“I have no delight in them”;
