'Happen' in the Bible

Whatever has happened, will happen again; whatever has been done, will be done again. There is nothing new on earth.

Then I told myself, "Whatever happens to the fool will happen also to me. Therefore what's the point in being so wise?" And I told myself that this also is pointless.

For he has absolutely no knowledge what will happen, since who can declare to him when it will come about?

The fool overflows with words, and no one can predict what will happen. As to what will happen after him, who can explain it?
