James 2:10; James 3:2; James 3:3; James 3:6

10 For whoever keeps the whole law and yet stumbles in one point, he has become guilty of all.

2 For we all stumble in many ways. If anyone does not stumble in what he says, he is a perfect man, able to bridle the whole body as well.

3 Now if we put the bits into the horses' mouths so that they will obey us, we direct their entire body as well.

6 And the tongue is a fire, the very world of iniquity; the tongue is set among our members as that which defiles the entire body, and sets on fire the course of our life, and is set on fire by hell.
