Ecclesiastes 9:5

“His sons achieve honor, but he does not know it; Or they become insignificant, but he does not perceive it.

There is no remembrance of earlier things; And also of the later things which will be, There will be for them no remembrance Among those who will come later still.

For there is no remembrance of the wise man along with the fool forever, inasmuch as in the coming days all will be forgotten. And how the wise man dies with the fool!

So then, I have seen the wicked buried, those who used to go in and out from the holy place, and they are soon forgotten in the city where they did thus. This too is vanity.

Whatever your hand finds to do, do it with all your might; for there is no working or explaining or knowledge or wisdom in Sheol where you are going.
