To deliver thee from the way of the evil man, from the man that speaketh froward things;
– Proverbs 2:12
[V]erses 12-15 provide example of the danger wisdom protects us from. The evil man is a calamitous man who brings pain and unhappiness to others. He has a way, or a course of life, and that way brings harm to others. The second clause explains how the evil man hurts others. He speaks forward things. Froward things are perverse things or things that are contrary to right and good things. His way and speech are bent away from wisdom and so he harms those who hear him. However when wisdom enters into our hearts, we are preserved and kept by it from such danger.
