'Happen' in the Bible

No one remembers the former events, nor will anyone remember the events that are yet to happen; they will not be remembered by the future generations.

So I thought to myself, "The fate of the fool will happen even to me! Then what did I gain by becoming so excessively wise?" So I lamented to myself, "The benefits of wisdom are ultimately meaningless!"

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

yet a fool keeps on babbling. No one knows what will happen; who can tell him what will happen in the future?

Divide your merchandise among seven or even eight investments, for you do not know what calamity may happen on earth.
