My wounds stink and are corrupt because of my foolishness. Psalms 38:5
The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.

Surely the serpent will bite without enchantment; and a babbler is no better.
The words of a wise man’s mouth are gracious; but the lips of a fool will swallow up himself.
The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness.
