A fool’s mouth is his destruction, and his lips are the snare of his soul.
– Proverbs 18:7
A fool’s speech betrays his lack of wisdom, but also brings him into trouble (Proverbs 12:13; 13:3). The word for snare refers to a noose for catching animals. The fool lays a trap for himself by his unrestrained and foolish speech. He is caught in the trap of his own making like the one who foolishly enters into suretyship (Proverbs 6:1-2).
