One generation passeth away, and another generation cometh: but the earth abideth for ever.

Yea, I was weary of all my labour, which I had taken under the Sun, because I should be fain to leave them unto another man, that cometh after me.

Forsomuch as a man should weary himself with wisdom, with understanding and opportunity, and yet be fain to leave his labours unto another, that never sweat for them. This is also a vain thing and a great misery.

I also realized that all [of the] toil and all [of] the skillful work that is done--it [is] envy between one man and {another}. This also [is] vanity and chasing wind!

I turned again and saw another vanity under the sun.

For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up.

Someone cometh out of prison, and is made a king; and another which is born in the kingdom, cometh unto poverty.

If you see oppression of the poor and perversion of justice and righteousness in the province, don’t be astonished at the situation, because one official protects another official, and higher officials protect them.

This is another misfortune: Just as he came, so will he go. What did he gain from toiling for the wind?

In the day of prosperity, rejoice! But in the day of adversity, consider! For God made one in place of another so that mortals cannot find out what will happen {in the future}.

Behold, this have I found, saith the Preacher, laying one thing to another, to find out the account;

Surely no one knows the future, and no one can tell another person what will happen.

All this have I seen, and applied my heart unto every work that is done under the sun: there is a time wherein one man ruleth over another to his own hurt.

Here is another enigma that occurs on earth: Sometimes there are righteous people who get what the wicked deserve, and sometimes there are wicked people who get what the righteous deserve. I said, "This also is an enigma."

It happeneth unto one as unto another; It goeth with the righteous as with the ungodly; with the good and clean as with the unclean; with him that offereth as with him that offereth not; like as it goeth with the virtuous, so goeth it also with the sinner; As it happeneth unto the perjured, so happeneth it also unto him that is afraid to be foresworn.

Here's another tragedy that I've observed on earth, a kind of error that comes from an overseer:
