'Happen' in the Bible

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.

I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favor to men of skill; but time and chance happen to them all.
