'Excessively' in the Bible

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!"

Don’t be excessively righteous, and don’t be overly wise. Why should you destroy yourself?

Don’t be excessively wicked, and don’t be foolish. Why should you die before your time?
