James 3:3-6

We put bits into the mouths of horses so that they will obey us, and with it we can turn their whole body. Though ships are large and driven by strong winds, the pilot can turn the whole ship with a very small rudder. So it is with our tongue, itself a small part of our body, yet it boasts great things. Consider this: a small spark can spread to become a forest fire. And the tongue is a fire, full of unrighteousness, able to corrupt your whole life. It can set the course of your life on fire, set on fire by hell itself.
