Proverbs 2:11 (KJV)

Then shalt thou understand righteousness, and judgment, and equity; yea, every good path.

When wisdom entereth into thine heart, and knowledge is pleasant unto thy soul;

Discretion shall preserve thee, understanding shall keep thee:

To deliver thee from the way of the evil man, from the man that speaketh froward things;

Who leave the paths of uprightness, to walk in the ways of darkness;
