'Happens' in the Bible

The wise man's eyes are in his head, and the fool walks in darkness -- and yet I perceived that one event happens to them all.

Then I said in my heart, "As it happens to the fool, so will it happen even to me; and why was I then more wise?" Then I said in my heart that this also is vanity.

For that which happens to the sons of men happens to animals. Even one thing happens to them. As the one dies, so the other dies. Yes, they have all one breath; and man has no advantage over the animals: for all is vanity.

There is a vanity which is done on the earth, that there are righteous men to whom it happens according to the work of the wicked. Again, there are wicked men to whom it happens according to the work of the righteous. I said that this also is vanity.
