'Overmuch' in the Bible

Then said I in my heart: As it comes to the foolish man, so will it come to me; so why have I been wise overmuch? Then I said in my heart: This again is to no purpose.

Be not righteous overmuch; neither make thyself overwise: why shouldest thou destroy thyself?

Be not overmuch wicked, neither be thou foolish: why shouldest thou die before thy time?
